Question

Use words to describe the following sequence. Then find the next three numbers in the sequence .49, 69, 81, 100.

Answer 1

The numbers (not counting 69) are all perfect squares. They are 7 squared, (what should be, possibly) 8 squared, 9 squared, and 10 squared. The next three numbers in the sequence would then be 121, 144, and 169.
