Series problems

In each step, element at the upper-right position gets enlarged, inverts vertically and reaches the lower-left corner; the existing element at the lower-left position, is lost and a new small element appears at the upper-right position.

In each step, the elements move in the sequence.

In each step, the CW-end element moves to the ACW-end position.

Both the larger and the smaller squares move to the adjacent corner ACW in each turn. Also, the shading in the smaller square moves 1, 2, 3, 4, 5, ... steps ACW sequentially and the shading in the larger square moves 1, 2, 3, 4, 5,.... steps CW sequentially.

One, two, three, one, two, three.....arcs get inverted sequentially. This inversion takes place in an ACW direction.

Similar figure reappears in every second step. Each time the first figure reappears, the elements interchange positions in the order : . And, each time the second figure reappears, the elements interchange positions in the order :

In One step, the middle element rotates through 180 ^o and in the next step, the other two elements rotate through 180 ^o. The two steps are repeated alternately.

The central arrow rotates 90 ^oACW and 45 ^oCW alternately. The half-arrow moves half-a-side of the square boundary in a CW direction and its head turns to the other side of the line in each step.

The 'T' shaped large element rotates 90 ^oCW in each step. The two small symbols interchange positions and the symbol that reaches the upper position gets replaced by a new one.

In the first step, the lowermost line segment is converted into a curve. In the second step, the second line segment also gets converted into a curve and the (existing curve is inverted. In each subsequent step, all the elements (line segments and curves) move in the sequence
