HELP MEEE WHATS THIS QUESTION

What is the difference between the 15th square number and the 8th square number?

Answer 1

`\huge\boxed{161}`

Let's start by finding the first 15 perfect square numbers (
`1^2, 2^2, 3^2, ...`):

`1,4,9,16,25,36,49,\bold{64},81,100,121,144,169,196,\bold{225}`

Next, we just need to find the difference between the 15th perfect square number and the 8th perfect square number, which I've made bold in the list above.

`225-64\\\boxed{161}`
