Question

the sum of two consecutive odd number are 8.find the number

Answer 1

let 2n+1,2n+3 are 2 odd numbers
sum=8
2n+1+2n+3=8
4n+4=8
4n=8-4
4n=4
n=1
2n+1 = 2(1)+1 = 2+1=3
2n+3= 2(1)+3= 2+3=5
numbers are 3,5

Answer 2

let one number be x
therefore other no. = x +2

ATQ

x + x + 2 =8
x + x = 8 - 2
x + x = 6
2x = 6
x = 6/2
x = 3

therefore one no. = x = 3

hence other number = x + 2
= 3 + 2
= 5

therefore 3 and 5 answer

to check

LHS = 3 + 5
= 8

RHS = 8

8 = 8
LHS = RHS
Hence verified

Hope this answer helps you and happy friendship day ☺☺
