Same setup as before. Just assign a variable to the smallest and then make the larger a function of the smallest by adding 2 to each.
x is the smallest odd integer
x + 2 is the next
x + 4 will be the third.
Sum of the smallest and four times the largest is 61, so that is our equation;
x + 4(x+4) = 61
x + 4x + 16 = 61
5x = 45
x = 9
so the next will be 11, and the next 13
But let's check it to be sure;
(I caught my own error checking it this way)
9 + 4 (13) = 61
So it checks
