Paragraph: Another type of sequence question involves a series of letters in a pattern. Usually, these questions use the letters' alphabetical order as a base. To make matters more complicated, sometimes subscript numbers will be thrown into the letter sequence. In these series, you will be looking at both the letter pattern and the number pattern. Some of these questions ask you to fill the blank in the middle of the series; others ask you to add to the end of the series.Question: B2CD_____BCD4 B5CDBC6D\mathrm{B}_2 \mathrm{CD}\_\_\_\_\_ \mathrm{BCD}_4\mathrm{~B}_5 \mathrm{CD}\mathrm{BC}_6 \mathrm{D}
