Francisco Bernard · Answer 1

This is the concept of geometric series. We are required to find the recursive formula for year n. Here we will use the formula;

nth=ar^ (n-1)

where;

a=first term

r=common ratio

n=nth term

Thus

a=8.50

r = (8.85) / (8.50) = 1.0412

thus the formula will be:

nth=8.50 (1.0412) ^n

Jason Riggs · Answer 2

The answers to the question above are "a1=8.5; an=an-1+0.35" and "f (n) = 8.5 + 0.35 (n - 1) " which is the recursive rule and the explicit rule of the sequence. The Recursive rule could be started with a different number other than the 8.5 but the explicit rule always uses the 8.5 as the starting number.
