Dev - C++ - hacer un programa tal que escribo 5 numeros y se le sumen 2 luego 4 y luego 6

A       A+2      A+4      A+6

3         5             7           9

6         8           10         12

9        11          13         15

12     14          16         18

15     17          19          21
