Hola como estas:
Explicación paso a paso:
Fórmula:
[tex]t_{n} = t_{1}[/tex] × [tex]r^{n-1}[/tex]
Reemplazando:
10 = [tex]t_{1}[/tex] × [tex]r^{2 - 1}[/tex]
20 = [tex]t_{1}[/tex] × [tex]r^{4 - 1}[/tex]
Operando se tiene:
10 = [tex]t_{1}[/tex] × [tex]r^{ 1}[/tex]
20 = [tex]t_{1}[/tex] × [tex]r^{3}[/tex]
Dividiendo de arriba hacia abajo:
2 = [tex]r^{2}[/tex]
±[tex]\sqrt{2}[/tex] = r
[tex]\sqrt{2}[/tex] = r
