Concept:
This series is based on the Cyclic Rotation of elements within a fixed structure. In such problems, elements move in a specific direction (clockwise or counter-clockwise) while maintaining their relative order.
Step 1: Identifying the movement of letters.
Let's track the letters R, T, L, J from one box to the next:
Box 1 to Box 2: R moves from Top $\rightarrow$ Right. T moves from Left $\rightarrow$ Top. J moves from Bottom $\rightarrow$ Left. L moves from Right $\rightarrow$ Bottom.
This indicates a 90° clockwise rotation of all letters.
Step 2: Verifying the rotation.
Box 2 to Box 3: T (Top) moves to Right. J (Left) moves to Top. L (Bottom) moves to Left. R (Right) moves to Bottom. (90° Clockwise)
Box 3 to Box 4: J (Top) moves to Right. L (Left) moves to Top. R (Bottom) moves to Left. T (Right) moves to Bottom. (90° Clockwise)
Step 3: Finding the final state.
To find the next figure, rotate Box 4 another 90° clockwise:
L (currently at Top) will move to the Right.
J (currently at Right) will move to the Bottom.
T (currently at Bottom) will move to the Left.
R (currently at Left) will move to the Top.
The resulting arrangement is: R (Top), T (Left), L (Right), J (Bottom).
