There were 18 seeds planted in the garden. After one week there were 324 seedlings. After 2 weeks there were 648 seedlings. If the number of seedlings grows at the same rate each week, how many seedlings will there be after 5 weeks?

Answers

Answer:

The answer is 1620 seedlings.

Step-by-step explanation:

The rate is that every one week, there is an increase of 324 seedlings. If it continued for 5 weeks, the total amount of seedlings will be 1620 seedlings. The equations I used to solve this are 648-324=324. 324x5=1620.

324*5 is 1620, so the answer is 1620
