Ch.3 Test Savings Accounts 1. Mike deposits $5,000 in a three-year CD account that yields 3.5% annual interest,
compounded weekly. What is his ending balance at the end of three years?

Step-by-step explanation:

5000 x 3 + 3.5% of 5000 x 3 = the answer

(n^3 - n)

= n(n-1)(n+1)

since it is divisible by 3 and 2 ,because it is a multiple 3 consecutive number

if, n-1 is odd then n+1 is also odd, then it is a multiple of 9

but if, n-1 is even then n+1 is also even, then it is a multiple of 4

so, largest multiple = max(9*2, 4*3) = max(18, 12) = 18
