Let 2 + 4 + 6 + 8 + . . . . . + 46 + 48 + 50 = x [notice that there are 25 terms in this sum]
Given: 1 + 3 + 5 + 7 + . . . . .+ 45 + 47 + 49 = k [notice that there are 25 terms in this sum as well]

Subtract the bottom equation from the top equation to get: 1 + 1 + 1 + 1 + . . . . . + 1 + 1 + 1 = x - k
Since the left side of both equations has 25 terms, the equation simplifies to get: 25 = x - k
Add k both sides of the equation: 25 + k = x

Answer: 25 + k

ASIDE: You would never see a Numeric Entry question like this on test day, Numeric Entry questions don't have non-numeric answers.
