Homework Help: Find the charge distribution pattern.

  1. Jan 23, 2012 #1
    1. The problem statement, all variables and given/known data

    1st terms = -e and positive e separated by d.
    2nd terms = Two units of charge e form a system of 3 point charges -e, 2e, and e (all d apart).

    The next terms are formed by changing the sign of the charge and then moving by one unit length.

    2. Relevant equations


    3. The attempt at a solution

    The actual problem is finding the E-field of the distribution of charges. However, I can't get past the wording of how it's telling me to set up the 3rd charge distribution. What exactly is the pattern here?
