Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. (15, 20, 25).
Logic : (First number + third Number) ÷ 2 = Second Number
First Set → (12, 15, 18) → (12 + 18) ÷ 2 = 15
Second Set →(10, 8, 6) →(10 + 6) ÷ 2 = 8
The same logic is followed in set of numbers given in option 1.
(15, 20, 25)→ (15 + 25) ÷ 2 = 20
Hence, (15, 20, 25) is the correct answer.
