Question

Look carefully for the pattern, and then choose which pair of numbers comes next.
28 25 5 21 18 5 14 _ _ _ _

• A. 11 5
• B. 11 7
• C. 11 8
• D. 5 10
• E. 10 11

Hint:

In many number series, a fixed number (like 5 here) acts as a "buffer" or "separator" between the actual mathematical progression.

Answer 1

The Correct Option is A

Step 1: Analyse options.
- The series follows a repeating pattern: subtract 3, then the number 5 is inserted as a separator. - $28 - 3 = 25$ - Separator: $5$ - $21 - 3 = 18$ - Separator: $5$ - Following this, the next subtraction from 14 is $14 - 3 = 11$, followed by the separator $5$.
Step 2: Conclusion.
The missing numbers are 11 and 5. Final Answer: (a) 11 5
