The RHS and the LHS elements interchange positions and the two central elements also interchange positions.

The elements move in the sequence

The elements move in the sequences and alternately.

All the elements together move one space to the right in each step and once they reach the rightmost position, then in the next step, they move to the leftmost position. Also, in the first step, the first (uppermost) and the third elements interchange positions; in the second step, the second and the fourth elements interchange positions and in the third step, none of the elements interchange positions. These three steps are repeated to continue the series.

The digits are removed one by one from the beginning and the end in order alternately so as to obtain the subsequent terms of the series.

In this series, the letters remain the same: DEF.The subscript numbers follow this series: 111, 112, 122, 222, 223, 233, 333, …

Study the pattern carefully. In the first segment, two letters face right and the next two face left. The first letter in the second segment repeats the last letter of the previous segment. The same is true for the third segment. But the forth segment changes again; it is the opposite of the first segment, so the last two letters must face right.

This is an analogy base question. The relation between first two segments is: the symbols “-” and “=” interchange their places and the symbols “+” and “ × ” interchange their places but “+” changes to “” as well. Similarly, apply this relation to third and fourth segments.
