Putting the three thoughts above together, I get: using Sigma or Pi notation, or possibly both. . After expanding the Pi notation into the full expression that it represents, the person working with that expression must follow the rules of algebra (or matrix algebra), and the index number of each factor would not have any effect on such rules. I have a student asking whether there is a symbol for exponentiation of a sequence? It seems that successive terms are growing smaller, since each is the previous term multiplied by a factor that is less than 1 and shrinking, so the series will converge (it shrinks faster than a geometric sequence with a common ratio that is less than one).
