Answer 6561.

The last number is the square of number 2 places before it.

Correct RMJ

There are two sequences arranged alternately. In each sequence the number is the square of the previous number in that sequence. 6,561 is the square of 81.

I think it is 4826.

The sequence seems to be reverse the first numbers then add the last two numbers.

Not certain why the first two sets are 6 numbers, then the next 3 sets are 4 numbers, then

a set of 3 numbers, then 2 numbers.

I put 3486 because there were 4 asterisks.

Your answer of 34826 makes more sense.
