Q. Type the missing number in this sequence:4, _, 8, 13, 20, 29, 40, 53
Identify Pattern: Identify the pattern in the sequence by checking the differences between consecutive terms. Difference between 8 and 13 is 5, between 13 and 20 is 7, between 20 and 29 is 9, and so on. The differences are increasing by 2 each time.
Calculate Difference: Calculate the difference needed before 8 to maintain the pattern.Since the difference between 8 and 13 is 5, the difference before 8 should be 3 (5−2).
Subtract to Find Missing Number: Subtract the calculated difference from 8 to find the missing number.8−3=5.
