Function h(n) = product of all even numbers from 2 up to n.
if h(100) ... and if p is the small prime factor of h(100) + 1.... what is p?
a) between 10 and 20
b) btwn 20 and 30
c) btwn 30 and 40
d) greater than 40
D is the answer
I took this to mean: h(100) + 1 = [ 2 x 4 x 6 x 8.. 100 ] + 1. Not sure what to do next.
Thanks for your help!
