If n is a natural number, then (6n 2 + 6n) is always divisible by: Options: A . &nbspBoth 6 and 12 B . &nbsp6 only C . &nbsp12 only D . &nbspNone of these

Answer: Option A 6n 2 + 6n = 6n(n + 1) Hence 6n 2 + 6n is always divisible by 6 and 12 (âˆµ remember that n(n + 1) is always even)

If n is a natural number, then (6n2 + 6n) is always divisible by:
