Consecutive numbers are numbers next to one another.
The odd numbers are 339 and 341
Let the smaller number be x.
So, the next number will be x + 2
The sum of the two numbers is:
[tex]\mathbf{x + x + 2 = 680}[/tex]
[tex]\mathbf{2x + 2 = 680}[/tex]
Subtract 2 from both sides
[tex]\mathbf{2x= 678}[/tex]
Divide both sides by 2
[tex]\mathbf{x= 339}[/tex]
So, the numbers are 339 and 341
