Question

ngular wall with building blocks. the top of the row has one block the second has three

Answer 1

Incomplete question, but given from research I believe this may be your question.

Jamila is making a triangular wall with building blocks. The top row has one block, the second row has three blocks, the third row has five, and so on. How many rows can she make with a set of 100 blocks?​

So, given with what we have, she has 100 blocks, and if we make a pyramid with what she started off with the first row of the pyramid with 1 block, and the second row with 3 blocks, we know the pyramid is made up of of odd numbers.
