Direction: Study the following sequence of letters, digits and symbols carefully:
8 · F W $ Y 5 6 G ? 7 1 E N # P 3 @ J B Δ 4 M R 9 2 + K
If the first seventeen elements are written in the reverse order followed by the next eleven elements, which element would be the fifth to the right of E?
- A5
- B6
- CG
- D?
Solution & Step-by-step Explanation
Let's count and isolate the first seventeen elements from the given sequence:
`8, ·, F, W, , Y, 5, 6, G, ?, 7, 1, E, N, #, P, 3` Reversing this block of 17 elements gives: `3, P, #, N, E, 1, 7, ?, G, 6, 5, Y,, W, F, ·, 8`
Appending the remaining 11 elements unaltered, the modified sequence becomes:
Locate the position of element
* 1st to the right:
* 2nd to the right:
* 3rd to the right:
* 4th to the right:
* 5th to the right:
Thus, the element fifth to the right of
`8, ·, F, W, , Y, 5, 6, G, ?, 7, 1, E, N, #, P, 3` Reversing this block of 17 elements gives: `3, P, #, N, E, 1, 7, ?, G, 6, 5, Y,, W, F, ·, 8`
Appending the remaining 11 elements unaltered, the modified sequence becomes:
3, P, #, N, E, 1, 7, ?, G, 6, 5, Y, $, W, F, ·, 8, @, J, B, \Delta, 4, M, R, 9, 2, +, KLocate the position of element
E in this updated series and find the fifth element to its right:* 1st to the right:
1* 2nd to the right:
7* 3rd to the right:
?* 4th to the right:
G* 5th to the right:
6Thus, the element fifth to the right of
E is 6.
