Question

find three concicutive odd number whose sum is 45​

Answer 1

Answer:

13,15,17

Step-by-step explanation:

let 1st odd no. be x

then 2nd odd no. = x+2

3rd odd no. = x+4

so... (x)+(x+4)+(x+2)=45

3x+6=45

3(x+2)=45

x+2=15

x=13

Answer 2

Answer :-

13 , 15 and 17 .

Given :-

Sum = 45

Solution :-

Let three consecutive positive integer be x+2 , x +4 , x + 6

Their sum is 45

A/Q

x + 2 + x + 4 + x + 6 = 45

→ 3x + 12 = 45

→3x = 45 - 12

→3x = 33

→ x = 11

hence, first number is x + 2

= 11 + 2

= 13

Second number is x + 4

= 11 + 4

= 15

Third number is x + 6

= 11 + 6

= 17

Verification :-

If we add this three odd number we get 45 as result.

→13 + 15 + 17 = 45

→ 45 = 45

hence, L. H. S = R. H. S
