Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. .
The logic followed here is:
-
Numerator × 4 + 3 = Numerator of next fraction
-
Denominator × 4 + 3 = Denominator of next fraction
7 × 4 + 3 = 31; 9 × 4 + 3 = 39
3 × 4 + 3 = 15; 5 × 4 + 3 = 23
Similarly,
11 × 4 + 3 = 47; 13 × 4 + 3 = 55
