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?

SOLUTION 1-7-1

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
