निम्नलिखित में से कौन सी संख्या दी गई श्रृंखला में प्रश्न चिह्न (?) का स्थान लेगी?
20, 25, 25, 35, 30, 45, ?, 55, 40
Detailed Solution & Logic
Correct Answer:
35
20, 25, 25, 35, 30, 45, ?, 55, 40
Split the series into two parts:
Odd positions: 20, 25, 30, 35, 40 =(+5)
Even positions: 25, 35, 45, 55 = (+10)
So, the missing number is: 35
