Which of the following pairs comes next in the series,

36, 31 , 29, 24, 22, 17, 15

Correct option is C

Given Series:

36, 31, 29, 24, 22, 17, 15

We need to find the next pair in the series.

Pattern Analysis:

1. Observe the difference between consecutive terms:

   • $36-31=5$
   • $31-29=2$
   • $29-24=5$
   • $24-22=2$
   • $22-17=5$
   • $17-15=2$

2. The differences alternate between 5 and 2.

Next Term:

• Since the last difference is $2$, the next difference will be 5.
• Subtract $5$ from $15$:$$15-5=10$$

1. The term after that will have a difference of $2$:
   • Subtract $2$ from $10$:$$10-2=8$$

Final Answer:

The next pair in the series is 10, 8
