Find a1 if sn = 89,800, r = 3.4, and n = 10. round to the nearest hundredth if necessary.

Step-by-step explanation:

We have a geometric  sequence with:

, , and

Where

Sn is the sum of the sequence

r is the common ratio

is the first term in the sequence

n is the number of terms in the sequence

The formula to calculate the sum of a finite geometric sequence is:

Then:

Now we solve for
