Explanation (1): Each part is taken alternatively from the first and last part of the original sequence with 3 characters each. Then the positions of three characters are changed in a way that the last of the three characters precede the first two characters in order. So the next part should be the three characters preceding the last three characters from the end. That is 864 and their position should be 486. So‘d’ is the correct answer.

Explanation (2): Two characters & and 8 appears thrice in the sequence.

Explanation (3): The numbers in the sequence are 6, 8, 8, 8, 6 and 4. Their average is 40/6= 6.66

Explanation (4): There are 15 letters between U and W in the given series. So, the middle letter is the eighth letter to the right of U, which is Y. Clearly, the tenth letter to the right of Y is C.

Explanation (5): In all other alternatives except (b), the second letter is two steps behind the first letter, while the third letter is four steps ahead of the second letter, in the given arrangement.

Explanation (6): N and L have just one letter between them in the given series as well as in the English alphabet.

Explanation (7):

Sum of the values of the vowels

= A + E + I + O + U

= 25 + 15 + 7 + 16 + 1 = 64

Explanation (8):

And letters are summation of the two numbers.

Explanation (9):

4 × 1 + 1 = 5

5 × 2 + 2 = 12

12 × 3 + 3 = 39

39 × 4 + 4 = 160

160 × 5 + 5 = 805

805 × 6 + 6 = 4836

Explanation (10): There are two alphabetical series here. The first series is with the first letters only: MNOPQ. The second series involves the remaining letters: UV, WX, YZ, AB, CD.
