If the difference of two consecutive numbers is 15 and the greater of them is X then the smaller number is

It's not possible for the difference of two consecutive numbers to be 15, by definition of 'consecutive', the difference is one

If, however, the word 'sum' is supposed to be at that place, then the numbers are 7 and 8

or, if we eliminate the "consecutive" then we have

If the difference of two numbers is 15 and the greater of them is X then the smaller number is X-15

To find the smaller number, we can first set up an equation using the information given. Let's assume the smaller number is represented by Y. According to the problem, the difference between the two consecutive numbers (X and Y) is 15.

Therefore, we can set up the equation:

X - Y = 15

If the greater number is represented as X, and we need to find the smaller number Y, we can rearrange the equation as:

Y = X - 15

So, the smaller number is X - 15.
