To determine the number of blocks in each row, we can observe that the number of blocks in each row is decreasing by 6 each time.
We can start by finding the pattern using the number of rows. We can determine the number of blocks in a row using this formula:
Number of blocks in a row = (60 - 6 * (row - 1))
Using this formula, we can find the number of blocks in the 8th and 10th rows.
For the 8th row:
Number of blocks = 60 - 6 * (8 - 1)
= 60 - 6 * 7
= 60 - 42
= 18
Therefore, there are 18 blocks in the 8th row.
For the 10th row:
Number of blocks = 60 - 6 * (10 - 1)
= 60 - 6 * 9
= 60 - 54
= 6
Therefore, there are 6 blocks in the 10th row.
