Problema Solution
If the first and third of three consecutive odd integers are added, the result is 69 less than five times the second integer. Find all three integers.
Answer provided by our tutors
Let the integers be x, x+2, x+4. If the first and third of three consecutive odd integers are added, the result is 69 less than five times the second integer. So,
x+x+4 = 5(x+2)-69.
2x +4 = 5x +10-69 = 5x -59.
3x = 59+4 = 63.
x = 63/3 = 21.
So, the numbers are: 21, 23, 25
