A perfect square is a number that is formed by multiplying a number by itself. For example, 9 is a perfect square because it can be formed by multiplying 3 by 3.
The first 15 perfect squares are:
1. 1
2. 4
3. 9
4. 16
5. 25
6. 36
7. 49
8. 64
9. 81
10. 100
11. 121
12. 144
13. 169
14. 196
15. 225
To find the next perfect square, simply add the next odd integer to the previous perfect square. For example, to find the next perfect square after 225, add 15+1=16 to get 241, which is a perfect square because it can be formed by multiplying 11 by 11.
