Choose x to represent the 1st number in the sequence.
The 2nd is x+2.
The 3rd is x+4
The 4th is x+6, and
The 5th is x+8

The sum of these 5 numbers is 5x + 2 + 4 + 6 + 8 = 310

Thus, 5x = 310 - (2+4+6+8)        or    5x = 310 - 20.     5x = 290

Then x comes out to be 58.

the 2nd number is 58+2 = 60.

The 3rd number is 60 + 2 = 62.   This is the answer.
