# Moessner's Theorem

Write down the positive integers in row one, cross out every th number, and write the partial sums of the remaining numbers in the row below. Now cross off every th number and write the partial sums of the remaining numbers in the row below. Continue. For every positive integer , if every th number is ignored in row 1, every th number in row 2, and every th number in row , then the th row of partial sums will be the th powers , , , ....
