A taxi driver had 24 fares to and from the airport last Monday. The price for a ride to the airport is $10 and the price for a ride from the airport is $15 the driver collected a total of $315 for the day

(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

529 and 531
