Show answer & explanation
Correct answer: D
There are 18 elements, so the first half has 9 elements.
Original sequence:
L, X, J, K, I, L, U, A, 5, 9, H, 2, T, %, 9, @, 1, #
Move the first 9 elements to the end. New sequence:
9, H, 2, T, %, 9, @, 1, #, L, X, J, K, I, L, U, A, 5
The 5th element from the right is at position 18 - 5 + 1 = 14, which is I.
7 positions to the left of position 14 is position 14 - 7 = 7.
The 7th element in the new sequence is @. Hence, Option D is correct.
