To find the nth term of a sequence, you first want to find the term to term difference.
-6, -1, 4, 9, 14
+5 +5 +5 +5
The term to term difference is the coefficient of n
5n
Now, we write out the sequence of 5n and work out the difference between the new sequence and the original
Always begin with n = 1
-6, -1, 4, 9, 14,
- 5, 10, 15, 20, 25,
-11 -11 -11 -11 -11
The nth term is 5n - 11
