Answer 1

The answer is 6, because the sequence would go 6,8,10,12.

Answer 2

Answer

6

Explanation

let n be the first even number in the sequence.

The 2nd term = n + 2

       3rd term = n + 2 + 2

                       = n + 4

    4th term = n + 4 + 2

                   = n + 6

The sum of these number = 36.

∴ n + (n +2) + (n + 4) + (n + 6) = 36

 4n + 12 = 36

 4n = 36 - 12

 4n = 24

n = 24/4

  = 6

The first term is 6.
