F 4 A % T 9 µ Z M 3 N # L & E 2 X C 7 G D * O 5 R ∞ H 1 J $ @ K 8 B

Which element is 4th to the right of the 6th element from the left end?

The correct option is 3.

To find the required element, let's look at the given sequence from left to right:
F, 4, A, %, T, 9, µ, Z, M, 3, N, #, L, &, E, 2, X, C, 7, G, D, *, O, 5, R, ∞, H, 1, J, $, @, K, 8, B

Step 1: Find the 6th element from the left end by counting from the start of the sequence:
1. F
2. 4
3. A
4. %
5. T
6. 9
So, the 6th element from the left end is 9.

Step 2: Find the element that is 4th to the right of this 6th element (9) by counting 4 steps to the right from 9:
1st to the right: µ
2nd to the right: Z
3rd to the right: M
4th to the right: 3

Alternatively, we can determine the position of the final element from the left end:
6 + 4 = 10

Counting to the 10th element in the sequence from the left end gives us:
F (1), 4 (2), A (3), % (4), T (5), 9 (6), µ (7), Z (8), M (9), 3 (10)

Therefore, the element is 3.
