1. The problem statement, all variables and given/known data(adsbygoogle = window.adsbygoogle || []).push({});

The following system of linear equations has infinitely many solutions.

{xi + xi+1 + xi+2 = 0 : 1 < i < 7}

3. The attempt at a solution

I feel like I have the capacity to solve this problem however I can't interpret what the question is even asking with all the i's in it.

If someone could just interpret the question for me that would be very helpful.
