A group is working on finding the mass of an unknown substance. They are using a digital balance. The first time they take the measurement the balance reads “2.5g.” They try again and the balance reads “2.6g.” They take one final reading and balance reads “2.5g.” They find the mean mass by adding up the values and dividing by three (the number of measurements taken). Their final answer for the mass of the substance is 2.53g.

(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
