Question

17	102	12
15	?	10

• A. 211
• B. 75
• C. 125
• D. 117

Answer 1

The Correct Option is B

The task is to determine the missing value in the logical sequence given in the table. Observing the first row, we have the numbers 17, 102, and 12. The given sequence follows a pattern: take the first number, multiply it by 6, and subtract a constant to obtain the middle number. Then take the middle number and divide it by the last number to verify the operation.

For the first row calculation:

• Step 1: Multiply the first number (17) by 6: 17 × 6 = 102
• Step 2: Subtract a constant: 102 - 0 = 102
• Step 3: Divide the middle number (102) by the last number (12) to verify: 102 / 12 = 8.5

Note that the exact division is not needed but helps affirm the pattern.

Apply the same logic to the second row where the first number is 15, and the last number is 10. The required middle number is unknown:

• Step 1: Multiply the first number (15) by 5: 15 × 5 = 75
• Conclusion: The missing number is thus 75 which fits into the given logical pattern based on multiplication of the first number by a constant.

Therefore, the missing number in the second row is 75.
