Answer:
Pattern 8 would have 64 squares.
Explanation:
Ok, I understand, Pattern 4 would have 16 squares, so we have to continue adding the pattern.
5 = 25, 6 = 36, 7 = 49, and 8 = 64. The key to this is each pattern number is multiplied BY ITSELF.
Hope this helps!
Sorry for being a little rude previous question, I didn't have a reference.
