Analyzing the Series Pattern

To find the missing term in the series DNN, FQQ, HTT, ___, LZZ, we need to analyze the pattern for each letter's position (first, second, and third) across the terms.

1. The Pattern of the First Letter

The sequence of the first letters is: D, F, H, ___, L.

This is an alphabetical series with a step of +2 between each letter.

D (4) → F (6) → H (8) → J (10) → L (12).

The first letter of the missing term is J.

2. The Pattern of the Second Letter

The sequence of the second letters is: N, Q, T, ___, Z.

This is an alphabetical series with a step of +3 between each letter.

N (14) → Q (17) → T (20) → W (23) → Z (26).

The second letter of the missing term is W.

3. The Pattern of the Third Letter

The sequence of the third letters is: N, Q, T, ___, Z.

This sequence is identical to the pattern for the second letter.

The third letter of the missing term is also W.

Conclusion

By combining the letters we found for each position, the missing term in the series is JWW.
