Show answer & explanation

Correct answer: D

Explanation

The correct answer is option 4 i.e. (5, 18, 27).

The Logic here is as follows:
Difference of 1st two numbers × 2 + 1 = Third number
In (3, 2, 3):
Difference of 1st two numbers (3, and 2) × 2 + 1 =
=(3-2)×  2 + 1
=1 ×  2 + 1
= 2 + 1 = 3 = Third Number
Similarly,
In (5, 18, 27):
Difference of lst two numbers (5, and 18) × 2 + 1 =
= (18 - 5) ×  2 + 1
= 13 × 2+ 1
= 26 + 1 = 27 = Third Number
Hence, the correct answer is '(5, 18, 27)'.
