Sorry, but 2 and 5 are not Mersenne Primes.
They are primes but not Mersenne Primes.
Now if you had stated the numbers 2^n-1 were prime for
n = 2, 3, 5, 7, 13, 17, 19, 31, 67, 127 and 257
... then you would be correct.
Mersenne Primes are primes that are represented as 2^n - 1. You cannot represent 2 and 5 in that form.
