Answers:

46. b. In this simple addition with repetition
series, each number in the series repeats
itself, and then increases by 12 to arrive at
the next number.
47. b. This is an alternating addition and subtraction
series, in which the addition of 4 is
alternated with the subtraction of 3.
48. e. Two patterns alternate here, with every
third number following the alternate pattern.
In the main series, beginning with 4, 3
is added to each number to arrive at the
next. In the alternating series, beginning
with 26, 6 is subtracted from each number
to arrive at the next.
49. c. This is an alternating addition series that
adds 5, then 2, then 5, and so on.
50. d. In this simple subtraction with repetition
series, each number is repeated, then 3 is
subtracted to give the next number, which is
then repeated, and so on.
