Answer:


26. b. This is a simple addition series, which
begins with 2 and adds 6.
27. a. This is an alternating subtraction series with
the interpolation of a random number, 5, as
every third number. In the subtraction series,
3 is subtracted, then 4, then 3, and so on.
28. e. This is a simple alternating addition and
subtraction series. First, 3 is added, then 1 is
subtracted, then 3 is added, 1 subtracted,
and so on.
29. b. This is a simple subtraction series in which a
random number, 85, is interpolated as every
third number. In the subtraction series, 10 is
subtracted from each number to arrive at the
next.
30. c. Here, every other number follows a different
pattern. In the first series, 6 is added to each
number to arrive at the next. In the second
series, 10 is added to each number to arrive at
the next.
