How do you solve problems involving sequence? Discuss the mathematics concepts and principles applied when solving problems involving sequence
Step-by-step explanation:
Sequence is defined as arrangement f numbers in a specific or defined pattern. Sequence are categorized into
1) Arithmetic
2) Geometric
Arithmetic sequence are characterized by their common difference while Geometric sequence are characterized by their common ratio.
Given a sequance of numbers say;
T1, T2, T3...
The first term "a" of the sequence is T1
Common difference d = T2-T1 =T3-T2
Common ratio = T2/T1 = T3/T2
The formula for calculating nth term of an Arithmetic sequence is expressed as;
Tn = a+(n-1)d
a is the first term
n is the number of terms
d is the common difference
The nth term of a Geometric sequence is expressed as;
Tn = ar^{n-1}
r is the common ratio
Numbers are arranged in a sequence when they follow a predetermined or established pattern. Sequences can be divided into
1) Mathematics
2) Graphitic
Geometric sequences are characterized by their common ratio, whereas arithmetic sequences are distinguished by their common difference.
Suppose a sequence of numbers is given;
T1, T2, T3...
The sequence's initial term "a" is T1.
common distinction d = T2-T1 =T3-T2
T2/T1 Common Ratio T3/T2
The following is the formula for finding the nth term in an arithmetic sequence:
Tn = a+(n-1)d
The first term is a.
The number of terms is n.
d is the typical discrepancy
The nth term of a Geometric sequence is expressed as;
[tex]T_{n} =ar^{n-1}[/tex]
r is the common ratio

What is the inverse of the function f(x) = x +3
Answer:
h(x) = x-3
Step-by-step explanation:
The inverse of a function works such that f(h(x)) = x. Also, f(h(x)) = h(x) + 3. Thus, x = h(x) +3 -> h(x) = x-3

Answer:
Students
Step-by-step explanation:
solve for all the values of the interior angles
Answer:
x = 6
Step-by-step explanation:
measure of angle E: 5(6) + 8 = 38
measure of angle D: 6(6) + 8 = 44
measure of angle C: 180 - 82 = 98
check answers by adding all 3 angle measures to make sure they equal 180 degrees

Use intercepts to graph the linear equation 5x + 3y = 30.
Answer x=6 and y=10
Explanation:
Replace each variable in turn with 0 and solve
5x+3y=30 Put zero in place of x and solve for y
5(0)+3y=30
[tex]\frac{3y}{3} =\frac{30}{3}[/tex]
y=10 The y- intercept is 10
5x+3y=30 Put zero in place of y and solve for x
5x+3(0)=30
[tex]\frac{5x}{5} =\frac{30}{5}[/tex]
x=6 The x-intercept is 6

Tracy can type 45 words in 3 minutes. At that rate, how many minutes would it take Tracy to type 315 words?
Answer:
21 minutes
Step-by-step explanation:
The rate that she types is 15 words in a minute
315/15 =
21 or 21 minutes
Answer: It will take Tracy 21 minutes to type 315 words
Step-by-step explanation:
Set up a proportional relationship to solve for the number of minutes.
45 words = 3 mins
315 words = x mins.
[tex]\frac{45}{315} = \frac{3}{x}[/tex] Cross multiply
45x = 945 Divide both sides by 45
x = 21

Juan needs to take an Uber to get to the movies. The Uber charges $1.50 for the first mile, and then $1.55 for each mile after that. If the total charge is $10.49, then how far was Juan’s Uber ride to the movie?
Answer:
5.8 miles were travelled by Juan's Uber ride to the movie.
Step-by-step explanation:
Let x = miles travelled by Juan
Charges for first mile = $1.50
Charges for each mile after first = $1.55
Total charge for Juan = $10.49
We need to find how many miles Juan covered?
The equation will be:
[tex]1.50+1.55(x)=10.49[/tex]
We will solve this equation to find value of x
Solving:
[tex]1.50+1.55(x)=10.49[/tex]
Subtracting 1.50 from both sides
[tex]1.50+1.55(x)-1.50=10.49-1.50\\1.55(x)=8.99\\x=\frac{8.99}{1.55} \\x=5.8[/tex]
So, 5.8 miles were travelled by Juan's Uber ride to the movie.

Answer:
6x-y
Step-by-step explanation:
Add the two expressions
Answer:
6x + -y
Lets simplify this step by step:
2x + 7y + 4x −8y
2x + 7y + 4x + −8y
Then we combine like terms
=2x + 7y + 4x + −8y
=(2x + 4x) + (7y + −8y)
= 6x + −y

Consider these functions:
f(x)=3x - 7
g(t)=1+1
What is the value of f(g(3))?
A.-1
B.0
C.3
D. 5
Answer:
A(-1)
Step-by-step explanation:
First, we will replace any x in g(x) with 3
g(x)=(3+1)/(3-1)=4/2=2
Thwn replace any x in f(x) with 2
f(x)=3(2)-7=6-7=-1 ⇒A
