In the following question, there is a letter series in which one...

Given series: GTZ, FSY, ERX, DQW, ? By analyzing the given series, we can say that from each letter 1 is subtracted from the place values to get the letters in the next letter group. The pattern is shown below: $$\begin{aligned} & \mathrm{G} \xrightarrow{-1} \mathrm{~F} \xrightarrow{-1} \mathrm{E} \xrightarrow{-1} \mathrm{D} \xrightarrow{-1} \mathrm{C} \\ & \mathrm{~T} \xrightarrow{-1} \mathrm{~S} \xrightarrow{-1} \mathrm{R} \xrightarrow{-1} \mathrm{Q} \xrightarrow{-1} \mathrm{P} \\ & \mathrm{Z} \xrightarrow{-1} \mathrm{Y} \xrightarrow{-1} \mathrm{X} \xrightarrow{-1} \mathrm{~W} \xrightarrow{-1} \mathrm{~V} \end{aligned}$$ So, the next term will be CPV. Hence, the correct answer is CPV.
