These items differ from Sets 1,2 , and 3 because they ask you to find the number that fits somewhere into the middle of the series. Some of the items involve both numbers and letters; for these questions, look for a number series and a letter series. Question: Look at this series: 15, \_\_\_\_ , 27, 27, 39, 39, . . . What number should fill the blank?

- A51
