Q. Type the missing number in this sequence:3, 4, 6, _____, 13, 18, 24, 31
Identify Pattern: To find the missing number in the sequence, we need to look for a pattern in the given numbers.Let's look at the differences between consecutive terms:4−3=16−4=2The differences seem to be increasing by 1 each time. Let's continue this pattern to see if it holds for the rest of the sequence.
Calculate Differences: We will now calculate the difference between the other consecutive terms to confirm the pattern:13−6=718−13=524−18=631−24=7It seems that the differences are not strictly increasing by 1, so our initial pattern does not hold. We need to re-evaluate the sequence to find the correct pattern.
Re-evaluate Sequence: Let's try a different approach. We will look at the differences again and see if there is another pattern:13−6=718−13=524−18=631−24=7The differences are alternating between increasing by 1 and decreasing by 2. If this pattern holds, the difference before 7 (between the missing number and 6) should be 5 (since it alternates and the next difference after 7 is 5).
Alternate Pattern: Now we will calculate the missing number using the pattern we have identified:If the difference between the missing number and 6 is 5, then the missing number is 6+5.Missing number = 6+5=11
Calculate Missing Number: Let's check if our found number fits the pattern:The difference between 13 and the missing number (11) should be 13−11=2.Now let's check the differences in the sequence with the missing number included:4−3=16−4=211−6=513−11=218−13=524−18=631−24=7The pattern of differences is now 110. This does not seem to be a clear pattern. It looks like there is a mistake in our reasoning. We need to find a consistent pattern.
