13

Right.
To find the number of blocks in the tower, we need to find the total sum of blocks in each row and then add them all up.
The first row has 1 block.
The second row has 4 blocks.
The third row has 7 blocks.
The fourth row has 10 blocks.
The fifth row has 13 blocks.
To find the total number of blocks, we can sum up the number of blocks in each row:
1 + 4 + 7 + 10 + 13 = 35
Therefore, there are 35 blocks in the tower.
