Question

find five consecutive odd integers if the sum of the first three integers is 7 more than the sum of the last 2

Answer 1

15, 17, 19, 21, 23

Explanation:

If you add the first three it is 7 more than the last 2

Answer 2

• 15, 17, 19, 21, 23

--------------------------------------

Let the five integers be x, x + 2, x + 4, x + 6, x + 8.

The sum of the first three integers is 7 more than the sum of the last two. Set up equation and solve for x:

• x + x + 2 + x + 4 = 7 + x + 6 + x + 8
• 3x + 6 = 2x + 21
• x = 21 - 6
• x = 15

Hence the integers are:

• 15, 17, 19, 21, 23
