Question

the sum of three consecutive odd number is 51 . find the number ​

Answer 1

Solution:-

Let the three consecutive odd numbers be x, x+2, x+4

Sum of odd numbers is 51

x + (x+2) + (x+4) = 51

3x + 6 = 51

3x = 51 - 6

3x = 45

x = $\sf\dfrac{45}{3}$

x = 15

Then the other two odd numbers are,

x + 2 = 17

x + 4 = 19

15, 17 and 19 are the three consecutive odd numbers

Answer 2

Answer:

Let three consecutive numbers x, x+1, x+2

Proof..from down the number 16

16+17+18=51

Solution..

(x +x+2+x+3)=51

3x+6=51

3x=51-6

3x=45

x=16
