[1176],[188],?,[122],[111]\left[\frac{1}{176}\right], \left[\frac{1}{88}\right], ?, \left[\frac{1}{22}\right], \left[\frac{1}{11}\right]

Show answer & explanation

Correct answer: B

Explanation

The correct answer is option 2 i.e. [144]\left[\frac{1}{44}\right].

[1176],[188],?,[122],[111]\left[\frac{1}{176}\right], \left[\frac{1}{88}\right], ?, \left[\frac{1}{22}\right], \left[\frac{1}{11}\right]

Logic: Multiply each fraction by 2 to get the next fraction.

1/176 × 2 = 1/88

1/88 × 2 = 1/44

1/44 × 2 = 1/22 

1/22 × 2 = 1/11
