Question

The sum of three consecutive integers is 81. Find the integers.​

Answer 1

(x-1) + x + (x+1) = 81, or, which is the same, 3x = 81. Hence, x = 81%2F3 = 27. So, your numbers are 26, 27 and 28.

Answer 2

Answer:

The three consecutive integers are $27,28,29$ respectively.

Explanation:

Let three consecutive numbers be $n,n+1,n+2$.

According to given question,

Sum of three consecutive integers is $81$.

$n+n+1+n+2 = 81$

                 $3n+3 = 81$

                  $3n= 81-3$

                   $3n = 78$

                    $n = \frac{78}{3}$

                     $n = 27$

Therefore,value of three consecutive integers will be

•     $n = 27$

• $n+1 = 27+1$

                 $= 28$

• $n+2 = 27+2$

                 $= 29$

Therefore the integers are $27,28,29$ respectively.
