Answers:

76. a. This series consists of letters in a reverse
alphabetical order.
77. b. This is an alternating series in alphabetical
order. The middle letters follow the order
ABCDE. The first and third letters are
alphabetical beginning with J. The third letter
is repeated as a first letter in each subsequent
three-letter segment.
78. b. Because the letters are the same, concentrate
on the number series, which is a simple 2, 3,
4, 5, 6 series, and follows each letter in
order.
79. d. The second and forth letters in the series,
L and A, are static. The first and third letters
consist of an alphabetical order beginning
with the letter E.
80. c. The first two letters, PQ, are static. The
third letter is in alphabetical order, beginning
with R. The number series is in
descending order beginning with 5.
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.
