The Nth 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 nth term is, remember one simple example and then the others will become obvious. 

A term in maths can mean many things but a term in a sequence just means the number at a certain position

NOTE:

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