# Line-breaking between arrays

I have these lists of values but they're all packed together, how can I add a new line between them? I've tried \ and \newline and all sorts but it would come up with errors. Thanks!

• Your code is rather elaborate, to put it politely. Why are there so many separate array environments? What are you trying to show? – Mico Nov 5 at 5:29
• This is the Secant Method - an iterative method to find the root of a function. I have to show the values of x for each iteration. I'm only a beginner so my knowledge on LaTex is still poor. – Achuan Chen Nov 5 at 7:43
