Two sets of numbers are given below. In each set of numbers, certain mathematical operation(s) on the first number result(s) in the second number. Similarly, certain mathematical operation(s) on the second number result(s) in the third number and so on. Which of the given options follows the same set of operations as in the given sets?
(NOTE: Operations should be performed on the whole numbers, without breaking down
the numbers into their constituent digits. E.g. 13 – Operations on 13 such as adding /
subtracting /multiplying to 13 can be performed. Breaking down 13 into 1 and 3 and
then performing mathematical operations on 1 and 3 is not allowed.)
5 - 6 - 10 - 20 ; 12 - 13 - 17 - 34

Correct option is A

Given:
5 - 6 - 10 - 20
12 - 13 - 17 - 34

Logic:
Step 1: +1 (Add 1 to the previous number)
Step 2: +4 (Add 4 to the previous result)
Step 3: Multiply by 2 (Multiply by 2 to get the next result)

Applying the logic to the given sets:
First Set: 5 - 6 - 10 - 20
5 → 6: Add 1 (5 + 1 = 6)
6 → 10: Add 4 (6 + 4 = 10)
10 → 20: Multiply by 2 (10 × 2 = 20)

Second Set: 12 - 13 - 17 - 34
12 → 13: Add 1 (12 + 1 = 13)
13 → 17: Add 4 (13 + 4 = 17)
17 → 34: Multiply by 2 (17 × 2 = 34)

Now, apply the same logic to the options:
Option A: 17 - 18 - 22 - 44
17 → 18: Add 1 (17 + 1 = 18)
18 → 22: Add 4 (18 + 4 = 22)
22 → 44: Multiply by 2 (22 × 2 = 44)
​
Final Answer: (A) 17 - 18 - 22 - 44
