Can someone me with (i) and (ii)?
-
(i) calculate the length of the inner lane of the track.
-
(ii) if each lane is 1m side calculate the length of each lane (2, 3, 4, 5).

(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

7
