The sum of two consecutive even numbers is 16 then the number is?
- 3, 4
- 4, 6
- 6, 7
- 7, 9
Explanation
Two find the two terms from a sum of two consecutive odd integers
Let the first term be, n
Then the next consecutive odd number is. n + 2
So the two terms sum to n + n +2 = 16
so 2n + 2 =16
Subtract 2 from both sides
2n = 14
Divide both sides by 2
n = 7 which is the first term
and n + 2 = 7 '
7 +2 = 9 is the second term
