Question

if n=1+x where x is the product of four consecutive positive integer, then which of the following are true?
1)n is odd
2) n is prime
3) n is a perfect square
4)none of these

Answer 1

your answer is option 1) n is a odd no.

Answer 2

Option (1) and (3) are correct.

Step-by-step explanation:

Let us take x= 1×2×3×4=24

Then n = 1+24=25

That is an odd number and a perfect square.

Again let x = 2×3×4×5=120

Then 1+120= 121

That is an odd number and a perfect square.
