In a pattern of blocks, the next image would contain how many blocks?

• A. 8 blocks
• B. 10 blocks
• C. 12 blocks
• D. 14 blocks

Answer: (B)

Patterns that grow by a constant amount from one image to the next are governed by a steady increase. In this pattern, the number of blocks goes up by 2 each step. So the next image should have two more blocks than the previous one. If the previous image has eight blocks, adding two gives ten blocks, which is why ten is the correct count. The other numbers would require a different amount added each step, which doesn’t match the consistent increase shown.
