The force, F, between two magnets varies inversely as the square of the distance, d, between them. F = 150 when d = 2.
Calculate F when d=4.

(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

answer is 67%

step-by-step explanation:

i think this could be a possible answer (1 / 84) -1

good luck! : d
