Find the common ratio of the infinite geometric series: \( \frac{-3}{5}-\frac{5}{3}-\frac{125}{27}-\dots\)
Mathtoo...The common ratio can be found by dividing a successive term by the preceding one
So [-5/3 ] / [ -3/5 ] = -5/3 * -5/3 = 25 / 9
Check for yourself that [-125 / 27] / [ -5/3 ] gives the same result...!!!
