prime 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
