Question

Identify the missing number and mark the answer in the OMR sheet.
2 5 7
4 7 5
3 6 ?

• A. 2
• B. 3
• C. 4
• D. 5
• E. 6

Hint:

In such number series questions, identify the relationship or pattern between numbers in rows and columns. In this case, it involved alternating addition and subtraction of 2.

Answer 1

The Correct Option is B

Step 1: Identify the pattern.
Looking at the first column: - 2, 4, 3. The difference between 4 and 2 is +2, and the difference between 3 and 4 is -1.
Looking at the second column: - 5, 7, 6. The difference between 7 and 5 is +2, and the difference between 6 and 7 is -1.
Looking at the third column: - 7, 5, ?. The difference between 5 and 7 is -2, so continuing the pattern, the missing number should be \( 5 - 2 = 3 \).
Step 2: Conclusion.
The correct answer is (B) 3, as it follows the established pattern in each column.
