Step-by-step explanation:

28   -22   38    30    -4

-26    -8   -34    20    -16

-6    -34   -24   -20    24

38   -32   36   -34    32

(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

77
