Answer:
The nth term is 4n+2
Explanation:
Formula:
term to term difference x n +/- term before first term
The term to term difference = +4
so 4n
Next, find the term before the first term
the first term in the sequence is 6, in order to find the term before 6 you must inverse the term to term difference
+4 becomes -4
6 - 4 = 2
In this sequence, the term before the first term (6) is +2
add the term before the first term to the term to term difference
4n + 2
(I tried to make the working as simple as possible, if this method is confusing for you there are easier methods you can use, but I prefer to use this method as it is faster)
