Question

The sum of 3 consecutive integers is 309. Determine the middle integer.

Answer 1

Hi WindowTrash14,

Solution:

To get the middle interger you need to divided the total by the 3 intergers:

309 / 3 = 103

103 x 3 = 309

Answer:

c) 103

Answer 2

Divide 309 by 3:

309 / 3 = 103

for the lower number subtract 1: 103 -1 = 102

for the higher number add 1: 103+1 = 104

The 3 numbers are 102, 103, 104

The middle number is 103.

The answer is C.
