Question

the sum of three consecutive odd natural numbers is 69 find the prime number out of this number

Answer 1

Let The middle No: of the odd Consecutive natural no's be x.
So x-2 and x+2 are the other two no:'s.

From The Question...

x+(x+2)+(x-2)=69
→3x=69
→x=69/3
→x=23

So The other two Numbers are 23+2=25. And 23-2=21.

But The prime among this is 23.


So 23 is the number you are Looking For....
Hope it Helps,
