Question : Directions: Select the option that represents the letters that when sequentially placed from left to right in the blanks will complete the letter series.
R_S_ _ _SGRT_G_TS_
Option 1: GTRTSGR
Option 2: RGTRSRG
Option 3: TGRSTRG
Option 4: TGRTSRG
Correct Answer: TGRTSRG
Solution : Given:
R_S_ _ _SGRT_G_TS_
To fill the series, we have to divide the series – R_S_ / _ _SG / RT_G / _TS _
Let's check each option –
First option: GTRTSGR; RGST / RTSG / RTSG / GTSR (No repeated pattern has been found.)
Second option: RGTRSRG; RRSG / TRSG / RTSG / RTSG (No repeated pattern has been found.)
Third option: TGRSTRG; RTSG / RSSG / RTTG / RTSG (No repeated pattern has been found.)
Fourth option: TGRTSRG; RTSG / RTSG / RTSG / RTSG (RTSG is repeated in the series.)
So, the series becomes→RTSGRTSGRTSGRTSG. Hence, the fourth option is correct.
