Q. Type the missing number in this sequence:2, 3, 6, 11, 18, _, 38, 51
Identify Pattern: Identify the pattern in the sequence.Look at the differences between consecutive terms to see if there is a pattern.3−2=16−3=311−6=518−11=7The differences are increasing by 2 each time.
Predict Next Difference: Predict the next difference in the pattern.If the pattern of differences continues, the next difference should be 7+2=9.
Find Missing Number: Find the missing number in the sequence. Add the predicted difference to the last known number in the sequence. 18+9=27 The missing number should be 27.
Verify Pattern Continues: Verify the pattern continues after the missing number.Add the next difference, which should be 9+2=11, to the missing number.27+11=38This matches the next number in the sequence, confirming our pattern.
