Question

2, 3, 6, 8, . . . is an example of an infinite alternating series.
a. True
b. False

Answer 1

The quick and simple answer to your question is "FALSE"

Answer 2

An alternating series is an infinite series that takes the form:
∑(-1)ⁿa_n
a_n>0 for every value of n. The signs of the general terms alternate between positive and negative.
Thus from the above definition, the series given by 2, 3, 6, 8, . . . does not fit the definition of alternating series.
