In the standard (x, y) coordi- nate plane, points P and Q
have coordinates (2,3) and
(12,-15), respectively. What are
the coordinates of the mid-
point of PQ?
O A. (6,-12)
O B.(6,-9)
O C. (6,-6)
ООО
O D. (7.-9)
E. (7,-6)

(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
