In terms of u, the sum u + w + y =


(A) 3u + 2
(B) 3u + 3
(C) 3u + 4
(D) 3u + 5
(E) 3u + 6


Since, letters represent consecutive integers
w = u +2
y = u + 4
u + w + y = u + (u +2) + (u + 4) = 3u +6

Answer E

Since the letters represent consecutive integers, we see that w = u + 2 and y = u + 4.
Thus, u + w + y = u + u + 2 + u + 4 = 3u + 6.

Answer: E

ANSWER:
=====

The value of number increases as we move towards right of the number line.
Here it states that the letters represent consecutive integers.

It clearly states that we need to find the value in terms of u.
Notice, w is 2 equal parts right to u and y is 4 equal parts right to u.

Hence, w = u +2
y = u + 4
Adding all of them.

u + w + y = u + (u +2) + (u + 4) = 3u +6

HEnce, Correct answer is E.
