If the sum of two consecutive odd number is 12 find them​
Fiesta28 [93]

Answer:

5 and 7

Step-by-step explanation:

<u>Fast and loose</u>: 12 is written as a sum of two odd numbers as 1+11; 3+9; 5+7. The only consecutive pair is 5 and 7

<u>Let's use algebra</u>: let's call 2n+1 the first and 2n+3 the second.

Their sum is 2n+1 +2n+3 = 4n+4 = 12. Thus, n+1=3 and n= 2. It means the 2 numbers are 2x2+1 =5 and 2x2+3 =7
