Jessica lives in a city and Anastasia lives in another city. Their houses are 68 miles apart and equidistant from a restaurant they are meeting at for lunch. The restaurant is (15x + 4) from Jessica's house and (10x + 4) from Anastasia's house. What is the value of x?

(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
