Can someone pls helppp

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
