Question 503508

The two main types of series/sequences are {{{arithmetic}}} and {{{geometric}}}. Some sequences are {{{neither}}} of these. 

It’s important to be able to identify what type of sequence is being dealt with.

And {{{arithmetic}}} series is one where {{{each}}}{{{ term}}} is equal the one before it {{{plus}}}{{{ some}}} number. For example: 5, 10, 15, 20, … Each term in this sequence equals the term before it with {{{5}}} added on. 

In contrast, a {{{geometric}}}{{{ sequence}}} is one where each term equals the one before it {{{multiplied}}} by a {{{certain}}} {{{value}}}. An example would be 3, 6, 12, 24, 48, … Each term is equal to the prior one multiplied by {{{2}}}. 

so, it's {{{neither}}} of these
