Marianne, arlene, tyler, and i worked together to complete a group project. marianne completed 1/5 marianne, arlene, tyler, and i worked together to complete a group project. marianne completed 3/10of the project. tyler and i finished the project and each did the same amount of work. what fraction of the project did i complete? a. 1/5 b. 1/10 c. 1/2 d. 1/4

(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

answer

the correct answer is
