Hi Kayla,
First determine your definition of a "prime number. (It can only be divisible by itself or 1, evenly.)
Replace "n" with a number and add 1 to it; then test the definition.
e.g., if N = 1; then 1 + 1 = 2 (Is 2 a prime number?)
try again, e.g.if N = 3; then 3 + 1 = 4. Can 4 be divided by anything else besides itself and 1? Yes; therefore, it is not a prime number. 4 divided by 2 divides evenly, confirming that 4 is not a prime number.
Test a few more, and I think you will be successful!
