Directions: Select the option that correctly replaces the question mark (?) to complete the letter series.

V, ?, F, K, P, U, Z, E

The correct option is A.

Step-by-step Explanation:

To find the missing letter in the series, let's look at the numerical positions of the given letters in the English alphabet (A = 1, B = 2, C = 3, ..., Z = 26):

V = 22
F = 6
K = 11
P = 16
U = 21
Z = 26
E = 5

Now, let's analyze the difference in position between consecutive known letters in the sequence:

From F (6) to K (11):
$6+5=11$
(Letter K)

From K (11) to P (16):
$11+5=16$
(Letter P)

From P (16) to U (21):
$16+5=21$
(Letter U)

From U (21) to Z (26):
$21+5=26$
(Letter Z)

From Z (26) to E (5):
$26+5=31$
$31-26=5$
(Letter E)

The pattern is adding 5 to the alphabetical position of each letter (wrapping around to the beginning of the alphabet after Z) to get the next letter.

Applying this rule to find the missing letter after V (22):

$22+5=27$

Since there are 26 letters in the alphabet, wrapping around gives:

$27-26=1$

The 1st letter of the alphabet is A.

Verifying the next step from A (1) to F (6):

$1+5=6$
(Letter F, which matches the given series)

Thus, the letter that replaces the question mark (?) is A.
