**PROBLEM 1-7-1 **

In the following pattern, 13 is in row 1. Suppose that the number pattern continues. In which row would you find 267? In which row would you find –153?

Multiples of 4 are in row 0

Therefore, 264 would be in row 0

264 + 3 = 267 so Row 0 + 3 = Row 3

**So 267 would be found in row 3**

-156 would also be found in row 0 as it also is a multiple of 4

-156 + 3 = -153 so Row 0 + 3 = Row 3

**So –153 would be found in row 3**
