Can you list all the prime numbers (in base 7) up to 100?
hint: there are only 21 of them.

2,3,5,11,13,23,25,31,35,41,43,53,55,61,65,71,73,83,85,91,95

Step-by-step explanation:

Prime numbers are neat.

Here they are:

2,3,5,11,13,23,25,31,35,41,43,53,55,61,65,71,73,83,85,91,95

Best,

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.
