In real, i mean what is : ( 2^n + 1 ) and n is originated from N

About all you can say with certainty (given what you've told us) is that it's an odd number except in the case that n = 0 ☺
Or are you thinking of the Mersenne primes?

2^n+1 such that n is a Natural number
gives us
the number after a power of 2.
so 2^1 = 2 ------------ 2^n+1= 3
2^2 = 4 ------------ 2^n+1= 5
2^3 = 8 ------------ 2^n+1= 9
2^4=16 ------------ 2^n+1= 17

n is the exponent......it can be any number
for example: 2^3+1=9
