Q. Type the missing number in this sequence:4, 6, 9, 13, _, 24, 31, 39
Identify Pattern: To find the missing number in the sequence, we need to determine the pattern. Let's look at the differences between consecutive terms.6−4=29−6=313−9=4It seems that the difference between consecutive terms is increasing by 1 each time.
Calculate Next Term: If the pattern continues, the difference between the next term after 13 and 13 itself should be 5. So, let's add 5 to 13 to find the missing number. 13+5=18
Verify Pattern: Now, let's check if this pattern holds for the next terms given in the sequence.24−18=631−24=739−31=8The differences are indeed increasing by 1, which confirms our pattern.
Final Answer: Therefore, the missing number in the sequence is 18.
