 To get the answer do this: 
2.5% of what is 2.21
2.5%x = 2.21
2.5/100x = 2.21
0.025x = 2.21
divide both sides by 0.025
0.025x/0.025 = 2.21/0.025
x = 88.4

Remember that finding terms in a geometric sequence is done by multiplying the previous term by a common ratio  . For example, we can say:
. For example, we can say:


We have  . To find
. To find  , let's multiply this term by
, let's multiply this term by  :
:

Now, let's use this to find all of our other terms:



Thus, our terms are 64, 80, 100, 125, and (625/4).
