You can solve this problem using algebra. Use x to represent the smaller number and x + 1 to represent the greater number. You use x + 1 to represent the larger number because it is 1 more than the smaller number.
x + (x + 1) = 115
2x + 1 = 115
2x = 114
x = 57
Therefore, the numbers are 57 and 58. You can plug 57 into x + 1 to find the larger number.
