You can put this solution on YOUR website! Consecutive integers are integers that follow one another. For example, 2,3,4,5,etc.... are consecutive integers
So algebraically, consecutive integers follow the form x, x+1, x+2, etc...
Since the sum of two consecutive integers is 239, this means:
Combine like terms on the left side
Subtract 1 from both sides
Combine like terms on the right side
Divide both sides by 2 to isolate x
Divide
So our first number is
So to find the next number, simply add 1 to it to get
So the next number is
