An example of a problem we experience regularly that is caused by an obsessive thought: finding three consecutive odd numbers whose sum is 147. In this case, the problem is that the sum is equal to 147.

So imagine that you want to find three consecutive odd numbers such that the sum is equal to 147. For example, 147 + 147 + 147 = 147.

A problem similar to finding three consecutive odd numbers in time is caused by a obsessive thinking that it is impossible to find one of the odd numbers in time. A problem similar to finding three consecutive odd numbers in time is caused by a obsessive thought that it is impossible to find one of the even numbers in time.

The answer is to take it a step further and start counting how many times a number has to be even, odd, or equal to 147 to have a certain sum. The sum is 147, so the number has to be even. In the process, you can use the formula to find out how many numbers have to be odd, even, or equal to 147 to have a certain sum.
