Linear Sequences

What is a sequence?
A sequence is a list of numbers that follow a pattern.

What is a linear sequence?
A linear sequence is a list of numbers that increases or decreases by the same amount each time.

Steps to Find the nth Term

1. Find the Common Difference (d):
   Subtract any term from the term that follows it.
   d = (any term) - (the term before it)
   
2. Find the First Term (a):
   Identify the first term in the sequence.
   
3. Use the Formula:
   The nth term (a_n) of a linear sequence is given by:
   a_n = a + (n - 1)d
   Where:
   a_n is the nth term.
   a is the first term.
   n is the term number.
   d is the common difference.
   
4. Simplify the formula to get the nth term.

Key Points:

• If the common difference (d) is positive, the sequence is increasing.
• If the common difference (d) is negative, the sequence is decreasing.
• The nth term formula allows you to find any term in the sequence.
