Explanation:

- We need to find numbers in the sequence, each preceded and followed by a consonant.

- Sequence: R Q D 8 H 9 L O P T E F M 6 I A 7 J 5 4 B U 2 G

- Examining each number:

- 8 is preceded by D (consonant) and followed by H (consonant).

- 9 is preceded by H (consonant) but followed by L, not consonant-consonant pair.

- 6 is preceded by M (consonant) and followed by I, not consonant-consonant pair.

- 7 is preceded by A (vowel) and followed by J (consonant), not preceded by consonant.

- 5 is preceded by J (consonant) and followed by 4, not consonant-consonant pair.

- 4 is preceded by 5 and followed by B, not consonant-consonant pair.

- 2 is preceded by B (consonant) and followed by G (consonant).

- As per the above analysis, there are indeed two numbers fitting the criteria.

- Correct Answer: Option:3, Two
