Draw the next picture in the sequence. How many small triangles are in step 25? How can you calculate this without drawing every step?

Korbyn, how did you calculate 75 triangles? There should be 25 small triangles just along the bottom of the 25th step. Wouldn't this mean there will be more than 75 small triangles in the entire large triangle?
