Explanation:

Let’s break down the pattern:

- 123 : 616

- 1 × 6 = 6

- 2 × 6 = 12

- 3 × 6 = 18

- These don’t directly relate to 616, so let’s try:

- 123 × 5 = 615 (not matching)

- Try writing digits: 123 ? 1,2,3

- 6, 1, 6 – is it doubling and adding?

- Let's check the difference: 616 - 123 = 493

- Not conclusive, let's move to second pair.

- 147 : 736

- Difference: 736 - 147 = 589

- Not matching with previous difference.

Let’s look for a digit pattern:

- Reverse the digits of the first number:

- 123 ? 321

- 147 ? 741

- 211 ? 112

Try adding 295 to reversed numbers:

• 321 + 295 = 616

• 741 + (-5) = 736

That breaks the pattern—so that's not correct.

Let’s check the options for 211:

- 996 – 211 = 785

- 1036 – 211 = 825

- 1046 – 211 = 835

- 1056 – 211 = 845

Let’s try summing digits:

- Sum of digits: 1+2+3=6 ? 616

- 1+4+7=12 ? 736

No clear pattern.

Let’s look at the last digit of second number:

- 616: last digit 6

- 736: last digit 6

- Among options only 996 ends with 6.

So, the correct answer is:

- Option 3, 996

- All statements explained:

- No consistent arithmetic pattern matching with the approach you took.

- The only recurring feature: Each output ends with 6, matching with 996.

Correct Option: Option 3, 996
