  # Understand Linear Number Sequences

In this worksheet, students will be tested on their understanding of linear number sequences by finding the given terms of different sequences and creating expressions that represent linear number sequences. Key stage:  KS 2

Curriculum topic:   Algebra

Curriculum subtopic:   Know Linear Number Sequences

Difficulty level:   #### Worksheet Overview

The nth term is a formula with 'n' in it that enables you to find any term of a sequence without having to go up from one term to the next.

n stands for the term number so to find the 10th term, we would just substitute 10 in the formula in place of 'n'

In this activity, you will be asked to find the given term.

Example 1:

Find the 6th term for n + 4=

6 + 4 = 10

So the 6th term is 10.

Example 2:

Find the 8th term for 2n - 4

(remember to always do the calculation in brackets first, BODMAS):

(2 x 8) - 4 = 12

16 - 4 = 12

The 8th term is 12.

In this activity, you will also be asked to write an expression using given numbers and letters.

Example:

The amount received by 6 children when a prize is shared equally between them.

Use the bold type letters and numbers to help:

We would create the expression:

a = p÷6

Now, over to you!
