Aditya sent a chain letter to 100 of his friends and asked them to forward it to their friends. Each day since then, the number of people who received the letter was 20% more than the day before.

(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

113.1

step-by-step explanation:

v=4

3πr3=4

3·π·33≈113.09734

its c

there is no following? ! lol
