Geometric series either get bigger or approach a single number. So, how do you know which it is? An interactive presents three different geometric series with varying common ratios. With the aid of patterns, pupils determine values of r that will make a series divergent or convergent. Learners determine the formula for the sum of the first n terms of a geometric series.
