Look at each of the monomials previously.

z2A

From a jump to z2A to y4B, it is:

one letter back lowercased: z -> y
Addition of 2: 2 + 2 = 4
one letter forward uppercased: A -> B

With this knowledge, look at v10E

First, go one letter back lowercased: v -> u
Next, add 2 to 10: 10 + 2 = 12
Finally, go up one letter uppercased: E -> F

You're answer is u12F, or A


hope this helps
the first one is correct 

A,B,C,D,E,F 

2,4,6,8,10,12 (counting by two)

z,y,x,w,v ( the alphabet backwards)
