A jar contains 2 blue cubes, 5 blue spheres, 2 green cubes, and 5 green spheres. If you select an object at random, what if the probability that the object is green or a cube? A. 5/14
B. 11/14
C. 1/7
D. 9/14​

C correct answer is c o think do

(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

if you was gonna solve for a, a is a   < -12
