The next two numbers in the given series 80, 10, 70, 15, 60, …….. are 

Correct option is A

Let's analyze the pattern in the given series: 80, 10, 70, 15, 60, ……...

Step 1: Identify the alternating sequences

• 80 → 70 → 60 → ? → ? (Decreasing pattern)
• 10 → 15 → ? → ? (Increasing pattern)

Step 2: Determine the rule for the decreasing sequence

• 80 → 70 (−10)
• 70 → 60 (−10)
• 60 → 50 (−10)
• 50 → 40 (−10)

So, the missing number in this sequence is 50.

Step 3: Determine the rule for the increasing sequence

• 10 → 15 (+5)
• 15 → 20 (+5)
• 20 → 25 (+5)
• 25 → 30 (+5)

So, the missing number in this sequence is 20.

Step 4: Choose the correct option

The next two numbers in the series are 20 and 50, which matches Option (A) 20, 50.
