Directions: In the following question, a number sequence is given with one term missing. Choose the correct term that will continue the same pattern and replace the question mark in the given sequence.Q.5 2,20,42,68,98,?
Correct answer: A. 132
- A. 132
- B. 130
- C. 134
- D. 136
Explanation
The sequence is 2, 20, 42, 68, 98, ?. Calculate the differences: 20 - 2 = 18, 42 - 20 = 22, 68 - 42 = 26, and 98 - 68 = 30. The pattern in the differences is 18, 22, 26, 30, each increasing by 4. Therefore, the next difference should be 34. Adding 34 to 98 gives 132. Options 130, 134, and 136 do not adhere to this consistent pattern of increasing differences and are thus incorrect.
