Dany jest ciąg geometryczny o wyrazie ogólnym an = -5*2n.
Oblicz iloraz tego ciągu.
an = -5^2n
n=1
a1 = -5^2 = 25
n=2
a2 = -5^4 = 625
a2/a1 = 625/25 = 25
iloraz naszego ciagu q = 25
po konsultacji z zadajacym * oznacza do potegi
a₁ = -5² = -25
a₂= -5⁴= -625
a₂ = -625 = 25
a₁ -25
iloraz ciagu q = 25
