Q. Type the next number in this sequence:\newline55, 66, 88, 1111, 1515, _\_
  1. Identify pattern: Identify the pattern in the sequence. Each number increases by a progressively larger amount. The differences between consecutive numbers are 11, 22, 33, and 44 respectively.
  2. Calculate next difference: Calculate the next difference by continuing the pattern. Since the last difference was 44, the next difference should be 55.
  3. Add to last number: Add this difference to the last number in the sequence. 15+5=2015 + 5 = 20.
