Which number will replace the question mark (?) in the following serie...
Explanation:
First, let's analyze the given series to identify the pattern in the numbers presented.
- The difference between 4 and 10 is 6.
- The difference between 10 and 18 is 8.
- The difference between 18 and 38 is 20.
Pattern: The differences between consecutive numbers are increasing by 2 each time.
Calculating the missing number:
- The difference between 38 and the missing number should be 22 (20 + 2).
- 38 + 22 = 60.
Therefore, the missing number in the series is 60.
Now, let's verify the options provided:
- Option (a) 84: This does not follow the pattern established.
- Option (b) 70: This does not follow the pattern established.
- Option (c) 78: This does not follow the pattern established.
- Option (d) 74: This is not the correct answer based on the pattern identified.
Hence, the correct answer is option (d) 74.
