How to make the code content of line 42 run similar to line 50. Let the five steps be shown line by line. In Python.

Codes here:

step_1=Latex(r"$P_{N+1}=rP_{N}$") step_2=Latex(r"$P_{N+1}=r(rP_{N-1}+m)+m$") step_3=Latex(r"$P_{N+1}=r^{N+1}P_{0}+m\sum_{r=0}^{N}r^{x}$") step_4=Latex(r"$P_{N+1}=r^{N+1}P_{0}+m\frac{(1-r^{N+1})}{(1-r)}$") step_5=Latex(r"$P_{N+1}=r^{N+1}P_0+\frac{m}{1-r}$")

: In [42]: step_1=Latex (r"$P_{N+1}=YP_{N} $") step_2=Latex (r"$P_ {N+1}=r (IP_{N-1}+m) +m$) step_3=Latex (r"$P_ {N+1}=> " {N+1}P_{0}+m\sum_ (r=0} * {N}r {x} $) step_4=Latex (r"$P_ {N+1}=r" {N+1}P_{0}+m\frac{(1-r{N+1})} {(1-1)} $") step_5=Latex (r"$P_ {N+1}=y" {N+1}P_0+\frac {m} {1-r} $) In [50]: Latex (r"$P_{N+1}=Y ` {N+1}P_O+\frac {m} {1-r}$") Out [50]: Pn+1 = pN+I P. + . m I-r
