When he invested money in a bank at a fixed rate of interest compounded annually. The equation below shows the value of investment after X years. f(x)=2,500(1.025)x. What is the average rate of change in the value of Whitney’s investment from the 10th year to the 15th year?

(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

the correct answer is 1: 2
