Question

Three consecutive integers have a sum of 87. Find the integers.

Answer 1

Answer:

• 28, 29, 30

Step-by-step explanation:

Let the integers be x- 1, x and x +1, then:

• x - 1 + x + x + 1 = 87
• 3x = 87
• x = 29

The integers are 28, 29, 30

Answer 2

Answer:

Let the numbers be (x-1), x and (x+1)

According to the above problem,

$(x - 1) + x + (x + 1) = 87 \\ 3x = 87 \\ \boxed{x = 29}$

Therefore, the numbers are 28, 29 and 30.
