3.4 James and John look at the following patterns:
Pattern 1 Pattern 2 Pattern 3
James says if he increases the pattern number by one, square that number and then
subtract the pattern number increased by one he will get the general formula.
John says he can derive the general formula for the number of blocks by taking the number
of columns in each pattern and multiplying if by the number of rows.
