How many numbers are in the list 433, 429, 425, ..., -103, -107?
Firstly add 111 to every number on the list so that the list becomes 544, 540, 536, ... , 8, 4. Then divide everything by 4 to get 136, 135, 134, ... , 1.
This list becomes 1, 2, 3, 4, ... , 135, 136. So, there are 136 numbers in this list.
Thank you!
