Answer 2

Answer:

Here's your Answer.

Step-by-step explanation:

Let one of the consequtive number be x. then the formula we can create is x, x + 1, x + 2.

x + x + 1 + x + 2 = 21

3x + 3 = 21

3x = 21 - 3

3x = 18

x = 18/3

x = 6

If x = 6

x + 1 = 6 + 1 = 7

x + 2 = 6 + 2 = 8

Therefore The three consecutive numbers are 6, 7, and 8 whose sum is 21.
