Solving the Letter Series Pattern

This question tests your ability to identify patterns in a sequence of letter groups. We need to find the missing group in the series: SCD, TEF, UGH, _____, WKL.

Analyzing the Series Structure

Let's break down the series by looking at the position of each letter group:

• The first group is SCD.
• The second group is TEF.
• The third group is UGH.
• The fourth group is the one we need to find.
• The fifth group is WKL.

We will analyze the pattern for each position (1st, 2nd, and 3rd letter) separately across the groups.

Step-by-Step Pattern Identification

1. Pattern in the First Letters:

Consider the first letters of each group: S, T, U, __, W.

Observing the alphabet, we see:

• S comes before T.
• T comes before U.
• W comes after the missing letter.

The pattern appears to be consecutive letters in the alphabet.

S + 1 letter = T

T + 1 letter = U

U + 1 letter = V

V + 1 letter = W

So, the first letter of the missing group is V.

2. Pattern in the Second Letters:

Consider the second letters of each group: C, E, G, __, K.

Let's look at the gaps between these letters in the alphabet:

• C to E: D is skipped (C + 2 letters = E).
• E to G: F is skipped (E + 2 letters = G).
• K comes after the missing letter.

The pattern seems to be advancing by two letters each time.

C + 2 letters = E

E + 2 letters = G

G + 2 letters = I

I + 2 letters = K

So, the second letter of the missing group is I.

3. Pattern in the Third Letters:

Consider the third letters of each group: D, F, H, __, L.

Let's examine the gaps:

• D to F: E is skipped (D + 2 letters = F).
• F to H: G is skipped (F + 2 letters = H).
• L comes after the missing letter.

This pattern also follows advancing by two letters.

D + 2 letters = F

F + 2 letters = H

H + 2 letters = J

J + 2 letters = L

So, the third letter of the missing group is J.

Determining the Missing Group

By combining the identified letters for each position, the missing group is formed by the first letter V, the second letter I, and the third letter J.

Therefore, the missing group in the series is VIJ.
