Simora [160]

Answer:

1+r+r^{2}+r^{3}+.....+r^{n-1} = \frac{1-r^{n}}{1-r}

Step-by-step explanation:

Taking the succession:

1+r+r^{2}+r^{3}+.....+r^{n-1}

You can multiply and divide by 1-r without chaging the result:

\frac{1-r}{1-r} (1+r+r^{2}+r^{3}+.....+r^{n-1})

Distributing the upper part of the fraction you have:

\frac{1}{1-r} (1-r+r-r^{2}+r^{2}-r^{3}+r^{3}-r^{4}+.....+r^{n-1}-r^{n})

As can be seen all the intermediate members will be canceled by a same member with opposite sign, only (1-r^{n}) will be left so:

1+r+r^{2}+r^{3}+.....+r^{n-1} = \frac{1-r^{n}}{1-r}
