(10.8). (12.15)
find the slope of the line through each pair of points .

(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

hey! so 1 (25) out of 4 (100) is 25 so your answer is 25%. it's like quarters!
