**Gray**, Wednesday, October 20, 2010 at 3:42pmThat sounds pretty advanced for an elementary class. One way you could start to solve this is to use a few different values for n and see what you get. Using n=1,2,3 we get p=7,13,19. Do that for a bunch of numbers (a spreadsheet program like Excel or Openoffice Calc will help with this) and see how many are prime.

**I. Kan**, Wednesday, October 20, 2010 at 4:24pmDo you think that the formula p=6n+1, where n, is a whole number, will produce a prime number more than 50% of the time? Give evidence to support your conclusion

solution

n= 1,2,3

formula P=6N+1

Now put n=1

p=6(1)+1

p=6+1

p=7

now put n=2

P=6n+1

p=6(2)+1

p=12+1

p=13

and so on so forth
