\(= r_1 s\)

\(\overline{C_2P_2}= r_2\)
\(\overline{C_3P_3}= r_3\)
\(= r_1 s\)
\(=r_1 s^2 \)
\(= r_2 s \)
\(=\left( r_1 s \right) s\)
\(\overline{C_1P_1}= r_1\)
\(\overline{C_2P_2}= r_2\)
\(\overline{C_3P_3}= r_3\)
Here \(\,0<s<1\)
\(\vdots \)
\(\overline{C_nP_n}= r_n = r_1 s^{n-1} \)
\(= r_1 s\)
\(=r_1 s^2 \)
\(= r_2 s \)
\(=\left( r_1 s \right) s\)
\(\,r_1 = \overline{C_1C_2} + \overline{C_2P_1},\)
\(\Rightarrow \overline{C_1C_2} = r_1-\overline{C_2P_1}\)
\(= r_1-r_1s\)
\(= r_1\left(1-s\right)\)
\(\,r_1 = \overline{C_1C_2} + \overline{C_2P_1},\)
\(\Rightarrow \overline{C_1C_2} = r_1-\overline{C_2P_1}\)
\(\,r_2 = \overline{C_2C_3} + \overline{C_3P_2},\)
\(\Rightarrow \overline{C_2C_3} = r_2-\overline{C_3P_2}\)
\(= r_1-r_1s\)
\(= r_1\left(1-s\right)\)
\(= r_1s-r_1 s^2\)
\(= r_1s\left(1- s\right)\)
\(\,r_1 = \overline{C_1C_2} + \overline{C_2P_1},\)
\(\Rightarrow \overline{C_1C_2} = r_1-\overline{C_2P_1}\)
\(\,r_2 = \overline{C_2C_3} + \overline{C_3P_2},\)
\(\Rightarrow \overline{C_2C_3} = r_2-\overline{C_3P_2}\)
\(= r_1-r_1s\)
\(= r_1\left(1-s\right)\)
\(= r_1s-r_1 s^2\)
\(= r_1s\left(1- s\right)\)
\(\overline{C_3C_4}= r_1 s^{2}\left(1-s\right) \)
\(\,r_1 = \overline{C_1C_2} + \overline{C_2P_1},\)
\(\Rightarrow \overline{C_1C_2} = r_1-\overline{C_2P_1}\)
\(\vdots \)
\(\overline{C_nC_{n+1}}= r_1 s^{n-1}\left(1-s\right) \)
\(\,r_2 = \overline{C_2C_3} + \overline{C_3P_2},\)
\(\Rightarrow \overline{C_2C_3} = r_2-\overline{C_3P_2}\)
\(= r_1-r_1s\)
\(= r_1\left(1-s\right)\)
\(= r_1s-r_1 s^2\)
\(= r_1s\left(1- s\right)\)
\(\overline{C_3C_4}= r_1 s^{2}\left(1-s\right) \)
Again \(\,0<s<1!\)
\(\overline{C_1C_2} =r_1(1-s)\)
\(\vdots \)
\(\overline{C_nC_{n+1}}= r_1 s^{n-1}\left(1-s\right) \)
\(\overline{C_2C_3} = r_1s\left(1-s\right)\)
\(\overline{C_3C_4}= r_1 s^{2}\left(1-s\right) \)
