Let's have N represent the first mystery number.

Since we need to find the next consecutive odd number, it will be two more than that number.

Here's a list of coonsecutive odd numbers starting from one: 1, 3, 5, 7, 9, 11, 13...etc.

Here you can see that the next consecutive odd number is two more than the last. This means the second mystery number can be written as N+2

They add up to 124, so now we can write this as an algebra problem.

N + N+2 = 124           ---Combine the N's to get 2N

2N + 2 = 124              ---Subtract 2 from both sides

2N = 122                     ---Divide both sides by 2 so we get N alone

N = 61

 

 

This tells us the first mystery number...but the second one was 2 more than that. Now we add two to 61 to find the second number

61+2= 63

 

Now we have the two numbers. 61 and 63.
