Question

the sum of three odd positive integers is 39 find the largest no.​

Answer 1

Answer: 15

Step-by-step explanation:

Let the three odd numbers be n,n+2 and n+4.

So n+(n+2)+(n+4)=39

3n+6=39

3n=33

n=11

Largest number is (n+4) which is 11+4=15.

Answer 2

Answer:

n+1 + n+3 + n+5=39

3n+9=39

3n=39-9

3n=30

n=30/3

n=10

largest number is n+5 = 15
