Question

7. The sum of three consecutive odd numbers is 51 find the number per

Answer 1

Step-by-step explanation:

Let the smallest of three consecutive number be x, thus other two consecutive numbers be x + 1 and x + 2.

As per the statement, sum of these three consecutive numbers is 51. As such

x + x + 1 + x + 2 = 51

3x + 3 = 51

3x = 51 - 3

3x = 48

x = 48/3

x= 16

The smallest of three consecutive number is 16. Other two numbers are

x + 1 = 16 + 1 = 17

x + 2 = 16 + 2 = 18

Thus three consecutive numbers are 16, 17 and 18

Answer three consecutive numbers are 16, 17 and 18

Let us check the correctness of answer by taking the sum of derived numbers, which should be 51.

16 + 17 + 18 = 51

51 = 51

Means answer is correct

Answer 2

X+x+1+x+2=51
3x+3=51
3x=48
X=16
16,17,18 is the right answer
