3(1) = 3
3(2) = 6
3(3) = 9
3(4) = 12
3(5) = 15
3(6) = 18
3(7) = 21
3(8) = 24
3(9) = 27
3(10) = 30
The set of number is in order, and gives you the product of the first ten numbers when multiplied with 3.
yes, for 12,21,30,216 > 10, you will reach them eventually
hope this helps
please enlighten me on what 3n 7n and 6n is there for, and maybe i can help for those too
