(43) The product of any three consecutive natural number is denoted by.(A) 6(B) 8(C) 20(D) 24

Answer»

Let the consecutive numbers be n, n+1, n+2

Their product would be n3+3n2+2n

Here it has been stated that n is a natural number. SO the value fo n could be anything from 1 to infinite.

let us test few values of n starting with 1, 2 and 3

n= 1 so n3+3n2+2n = 6 which is divisible by 6,

n= 2 so n3+3n2+2n = 24 which is also divisible by 6 and so on.

SO we may say that the the product of any 3 consecutive natural numbers is divisible by 6.
