Jeremiahs credit card has an apr of 22% calculated on the previous monthly balance. his credit card record for the last 7 months is shown in the table below

answer: 180

step-by-step explanation:

12-2=10

20-2=18

10x18=180

(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
