Part 1: Find the mean of this set of data.

Part 2: Find the mean absolute deviation of this set of data.

Part 3: Using complete sentences, explain what your results for part A and B mean.

(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

good job you smart son of a gun you are smarter that einstein. 7
