Given series: 9,2, 6561, 43046721
We need to determine the missing number in the series.
First, we note that 43046721=65616561=65612 and thus we suspect that each term is the square of the next term.
Let us determine the square of the first term 9:
92=81
Thus we suspect that the missing term is 81, which is confirmed by the fact that 8126561.
