**I. Kan**, Wednesday, October 20, 2010 at 4:31pmprime Numbers are 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43

prime Numbers are those, who must divided by itself and by 1

so n=2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97.............

now put the value of n in the formula

for example

p=6n+1

p=6(2)+1

p=12+1

p=13

fifty percent more this number should be 13/2=7.5

so 13+7.5=19 or 20 round it

so
