Find three consecutive odd integers such that the sun of the largest and twice the smallest is 25

Answers

Let's call the our odd numbers a, b, and c, in ascending order. It can be said then that b = a +2 (It is the next odd number after a) and c = a + 4 (It is the second consecutive number after a).


Additionally, we can say:

c + 2a = 25


Now, how about we substiute in the value for c we found in the first paragraph for c in the preceeding equation? This gives us:

(a + 4) + 2a = 25

  • Substitute

3a + 4 = 25

  • Add like terms

3a = 21

  • Subtract 4 from both sides

a = 7

  • Divide both sides by 3

We have found that the smallest number is 7. Substituting this into the equations we found in the first paragraph, we find:

b = 7 +2 = 9

c = 7 + 4 = 11


The numbers are 7, 9, and 11.

Answer:

The three correct numbers are 7, 9, and 11.
