Question

Jill is building a pyramid with her blocks.She wants to have 4 rows, each with 5 more blocks then the row above it.The final row will have1 block. How blocks will Jill need to use to build her pyramid

Answer

If the top level has one block, the second has six and that can only be two rows of three. The next level has eleven and that can only be one row, so this can never hold together to be a pyramid. Think of something else.
