Question

find three consecutive odd natural number whose sum is87

Answer 1

Here Friend,

Here Is Your Answer,

Let, first odd no. is = x

therefore, other two odd no.s will be (x+2) , (x+4).

Now,
x+(x+2)+(x+4)=87
3x + 6 = 87
3x = 81
x = 27

therefore, odd no.s will be 27, 29, 31.

Answer 2

Let the three consecutive odd natural numbers be (2x - 1) , (2x + 1) and (2x + 3)

As given, the sum of three numbers is 87.

Therefore;

2x - 1 + 2x + 1 + 2x + 3 = 87

6x + 3 = 87

6x = 84

x = $\frac{84}{6}$

x = 14

Hence the three numbers will be:

2x - 1 = 2 * 14 - 1 = 27

2x + 1 = 2* 14 + 1 = 29

and,

2x + 3 = 2*14 + 3 = 31
