Question

5. The product of a non-zero whole number and its successor is always?
a) even number b) Odd number c) Prime number d) Divisible by 5​

Answer 1

Answer:

a) even number.

Step-by-step explanation:

Let, a non zero whole number be 'n'.

then, the successor will be (n+1)

A/C

n(n+1) = n²+n

Putting n=1

1²+1 = 2 ( even number)

Putting n=2

2²+2 = 6 ( even number)

=> the product of a non zero whole number and its successor is always a even number.
