Is there a way to compare the current value with previous value using a for each loop?

Question

I'm able to do it using a for loop but I want to us a for each loop because I don't know the index length of the elements I'm looping.

When I use a for loop, I use the i to refer to the elements of my array. Like:
Current item: myArray[i]
Next item: myArray[i+1]
Previous item: myArray[i-1]

I know we have clever brains here so someone would know the answer
