Answer:
The answer is 64.
Step-by-step explanation:
Lets say the top row is x and the bottom row is y.
Since when x is 13 y is 104 and when x is 14 y is 112 that means the y value goes up by 8 every time.
when x=3: 16+8=24
when x=4: 24+8=32
when x=5: 32+8=40
when x=6: 40+8=48
when x=7: 48+8=56
when x=8: 56+8=64
Hope this helps you!!!!
