Question

{(2177)
The sum of three consicative odd hunbers is 51
find the
numbers.​

Answer 1

15,17,19

Step-by-step explanation:

Let numbers are a - 2, a, a + 2

Sum = 51

(a - 1) + (a) + (a + 1) = 51

a - 1 + a + a + 1 = 51

3a = 51

a = 51/3

a = 17

No. are 17-2 = 15 ,17,17+2 = 19

Answer 2

Answer:

the 3 consecutive odd no.s are 15,17,19

Step-by-step explanation:

let the 3 consecutive odd no.s be,

(2n-1),(2n+1),(2n+3)

given that, (2n-1)+(2n+1)+(2n+3) = 51

=> 6n+3 = 51

=> 6n = 51-3

=> 6n = 48

=> n = 48/6

=> n = 8

so, the 3 consecutive odd no.s are,

(2*8-1),(2*8+1),(2*8+3)

=> (16-1),(16+1),(16+3)

=> 15,17,19
