Answer:

The pattern the sequence follows is a perfect square, minus 2

Explanation:

esentially use ( n^2 - 2 ) to find the nth number in the sequence.

the 5th number ( n = 5 ), would look like ( 5^2 - 2 ), simplfiying to ( 25 - 2 ), then being 23.

The same applies to all numbers listed in the sequence.
