Okay, your answer is 182. You really do not need to look at the crazy stuff on the paper about the crazy numbers. Look at the graph. It is counting up by 20's on the left side. But on the right side, the whole time it is counting up by 13's. Your answer is 182.
Answer is B
Each number under the leaf side is the other half of the stem.
Therefore,
1 | 7 =1.7
1 | 3 =1.3
3 | 7 =3.7
So on and so forth.
