How do you find the Numbers? First, we can call the three consecutive integers: Because we know their sum (meaning if we add them together) is #105# we can write the following equation and solve for #n#: #3n + 3 - color(red)(3) = 105 - color(red)(3)#, #(color(red)(cancel(color(black)(3)))n)/cancel(color(red)(3)) = 34#. Integers are three types of numbers including negative integers, positive integers, and zero. x + 2 = 49 + 2 = 51. x + 4 = 49 + 4 = 53. Most of the time, we are only asked to find the consecutive integers which when added, must give the specified sum.
