title: What is the difference between a[n+1] and a[n]+1 inside an array?
body: <p>I looked and looked on the website to find the answer to this but I couldnt find it anywhere. </p>
  
  <p>However, what is the difference?</p>
  
  <p>Here is what I think.</p>
  
  <p>Say I have an array with five elements in it, a[5]. a[n+1] would be the second element, a[n+2] would be the third, etc. </p>
  
  <p>a[n]+1 would be, say I type in a number into the first element [n]. Say that number is 27, since a[n]+1 would equal 28. </p>
