Collect the souls of the dead every Full moon night.

Four souls with one soul every two nights equals four souls in eight nights.

4 * 2 = 8

Seven souls with one soul every two nights equals seven souls in fourteen nights.

7 * 2 = 14

Ten souls with one soul every two nights equals ten souls in twenty nights.

10 * 2 = 20

How is my math wrong?
