Sara has a balance on her credit card of $212.45. She writes a check for $165.45 towards her credit card balance. After she has paid, how much more money will she need to pay to have a zero balance?

(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

it's undefined because anything multiplied by 0 is 0. that said, 7 days is 168 hours
