Question

if three consecutive numbers whose sum is 12 then find the number
​

Answer 1

Answer:

         3, 4, 5

Step-by-step explanation:

Let x be the middle number.

Then the three consecutive numbers are x-1, x and x+1.

Their sum is 12  ⇒  (x-1) + x + (x+1) = 12  ⇒  3x = 12  ⇒  x = 4.

So the three consecutive numbers are:

  3, 4, 5

Answer 2

Let the three consecutive no. be = x, x +1 and x + 2

ATQ

x + x + 1+ x + 2 = 12

3x + 3 = 12

3x = 12 - 3

3x = 9

x = 3

Therefore three consecutive numbers are 3, 4 and 5
