Option D is correct. The correct option for the recursive formula is 
Given the sequence 10, 14, 18...
The first term is 10, hence
a1 = 10
The previous terms will be 
From the sequence, we can see that <em>4 is being added to the previous term to get the next term</em>. Hence the nth term will be expressed as:

Get the term before the first term 
If n = 1

Hence the correct option for the recursive formula is
