Divya and Miguel were asked to find an explicit formula for the sequence 80,40,20,10,..

In-s [12.5K]

Answer:

$a_n =80(0.5)^{n-1}$

Step-by-step explanation:

we know that

The explicit formula for a geometric sequence is written as:

$a_n = a_1(r)^{n-1}$

where

a_1 is the first term

r is the common ratio

we have the sequence

$80,40,20,10,..$

$a_1=80\\a_2=40\\a_3=20\\a_4=10$

$\frac{a_2}{a_1}=\frac{40}{80}=0.5$

$\frac{a_3}{a_2}=\frac{20}{40}=0.5$

$\frac{a_4}{a_3}=\frac{10}{20}=0.5$

therefore

$r=0.5$

substitute

$a_n =80(0.5)^{n-1}$
