If h(n) = 2*4*6*......n, where will the smallest prime factor of h(100)+1 lie?
A. Less than 10
B. Between 10 and 20
C. Between 20 and 30
D. Between 30 and 40
E. Greater than 40
The answer is most probably E, but I do not with 100% confidence (sorry!) and neither do I understand how to solve the question??
