Concept
This is a series problem. To solve this kind of problem, we first need to identify the pattern in the given terms and then execute the same for missing terms.
Given
We are given a series: R1ST, RS2U, RSV3, (?). RS5X.
Find
We are asked to find the missing term of the series.
Solution
To solve this problem, we first try to get the pattern among the given terms.
R1ST to RS2U:
R has remained constant.
1 is changed to 2.
S has remained constant.
T has changed to U.
2 has moved one step rightwards.
R2SU to RSV3:
R has remained constant.
S has remained constant.
1 is changed to 2.
U has changed to V.
3 has moved one step rightwards.
Going by the same pattern for the term "(?)"
RSV3 to "(?)"
R will remain constant.
S will remain constant.
3 will change to 4.
V will change to W.
4 will move one step rightwards.
So it can be 4RSW.
Now, we check this with the next term following the same pattern.
4RSW to RS5X.
R has remained constant.
S has remained constant.
4 is changed to 5.
W has changed to X.
5 has moved one step rightwards.
But this will be R5SX and not RS5X. This means the position of R is fixed.
Hence, the missing term will be R4SW and not 4RSW.
The missing term is R4SW.
