So now, what 4 letter words can be formed ending with "AIR"? Think of all the words from A to Z, considering which one lies above you. That is how we get to "HAIR". Now, which 5 letter word can be formed ending with "HAIR"? Starting with A to Z, we reach "CHAIR" and also, it lies below us. And the required answer is "CHAIR".

उत्तर : 2. "32"
व्याख्या :
Answer: B) 32 Explanation: Here the given series follows a pattern that, 22 - 0 = 4 32 - 1 = 8 42 - 2 = 14 52 - 3 = 22 62 - 4 = 32 Hence, the missing number is 32 Method 2 :: The difference between 4 and 8 is 4, the difference between 8 and 14 is 6, the difference between 14 and 22 is 8. So the next difference between 22 and the next number will be 10 since it follows (4,6,8,10 - add +2 each time) Hence, 22 + 10 = 32 is the missing number.
