Answers:

81. c. The first letters are in alphabetical order
with a letter skipped in between each segment:
C, E, G, I, K. The second and third
letters are repeated; they are also in order
with a skipped letter: M, O, Q, S, U.
82. a. In this series, the third letter is repeated as
the first letter of the next segment. The
middle letter, A, remains static. The third
letters are in alphabetical order, beginning
with R.
83. d. In this series, the letters remain the same:
DEF. The subscript numbers follow this
series: 1,1,1; 1,1,2; 1,2,2; 2,2,2; 2,2,3.
84. c. There are two alphabetical series here. The
first series is with the first letters only:
STUVW. The second series involves the
remaining letters: CD, EF, GH, IJ, KL.
85. a. The middle letters are static, so concentrate
on the first and third letters. The series
involves an alphabetical order with a reversal
of the letters. The first letters are in
alphabetical order: F, G, H, I, J. The second
and fourth segments are reversals of the
first and third segments. The missing segment
begins with a new letter.
