The formula for any geometric sequence is an = a1 · rn - 1, where an represents the value of the nth term, a1 represents the val

Answer:

$\huge\boxed{a_n=1\cdot(-2)^{n-1}}$

Step-by-step explanation:

$a_n=a_1r^{n-1}$

We have the geometric sequence: 1, -2, 4, -8, ...

Find the common ratio:

$r=\dfrac{a_2}{a_1}=\dfrac{a_3}{a_2}=...=\dfrac{a_n}{a_{n-1}}$

$a_1=1,\ a_2=-2$

substitute:

$r=\dfrac{-2}{1}=-2$

Substitute

$a_1=1;\ r=-1$

$a_n=a_1r^{n-1}$

$a_n=1\cdot(-2)^{n-1}$
