Show answer & explanation
Correct answer: D
To find the element exactly between J and D, we need to isolate the segment of the sequence starting at J and ending at D, and then identify the middle position.
Step-by-Step Analysis
Identify the Sequence:
The given arrangement is: J ^ F $ E I # M # K L Q @ W D
Locate J and D:
J is the 1st element.
Let's count the positions to D:
1(J), 2(^), 3(F), 4($), 5(E), 6(I), 7(#), 8(M), 9(#), 10(K), 11(L), 12(Q), 13(@), 14(W), 15(D).
Find the Middle Position:
There are 15 elements in total from J to D.
The middle position is the 8th element: (15 + 1)/2 = 8
Counting to the 8th element:
1:J, 2:^, 3:F, 4:$, 5:E, 6:I, 7:#, 8:M.
