Question

What’s the number of tiles going by?

Answer 1

The number of tiles is going by addition of 4

How to find the number of tiles

Using the function 4x + 1, we solve for the values of y

For x = 0

y = 4(0) + 1 = 1

For x = 1

y = 4(1) + 1 = 5

For x = 2

y = 4(2) + 1 = 9

For x = 3, y = 9 + 5 = 13

y = 4(3) + 1 = 13
