Hi,
I'm learning about sequences and series in my calc 2 textbook. I have a question about this definition:
A sequence {
} is called
increasing if {
} < {
} for all
. It is called
decreasing if {
} > {
} for all
. It is called
monotonic if it is either increasing or decreasing.
Should that read "if it is *neither* increasing or decreasing." ?
It looks like a typo, but I'm not sure, so I thought I would ask for clarification. I tried some google searches but couldn't find a clear definition.
Thanks!
