How do we know this? For the recursive definition, we need to specify a0. Then we need to express an in terms of an − 1. If we call the first term a, then a0 = a. For the recurrence relation, by the definition of an arithmetic sequence, the difference between successive terms is some constant, say d.

WebAs it turns out, the special properties of Groups have everything to do with solving equations. When we have a*x = b, where a and b were in a group G, the properties of a group tell us that there is one solution for x, and that this solution is also in G. a * x = b. a-1 * a * x = a-1 * b. (a-1 * a) * x = a-1 * b.
