Question

Leo's bank balances at the end of months 1, 2, and 3 are $1,500.00, $1,530.00, and $1,560.60, respectively. The balances form a geometric sequence. What will Leo's balance be after 9 months?

Answer 1

first, find the common ratio.

r=1530.00/1500=1.02

f(n)=f(1)r^n-1

f(9)=1500(1.02)^9-1

f(9)=1500(1.02)^8

f(9)=1757.49

Explanation:

Answer 2

$1,830.6 is your answer!

This is because; 30 × 9 ≈ 270 + 1,560.60≈1,830.6
