The `N^(th)` term of a sequence

The word term is difficult to understand because term can mean:

  • a number
  • a variable
  • a number times one or more variables

 

So term could be `6` or `y` or `3xy`, but it is usually in a formula between a +ve and a -ve sign as:

`5x+3+8y`

(See our Mammoth memory definition of term)

However, in sequences term means number.

 

To remember what the `n^(th)` term is, remember one simple example and then the others will become obvious.

NOTE:

This sequence 2, 4, 6, 8 has to be one of the most famous sequences ever.
