Determine if the sequence is geometric. If it is, find the common ratio, the 8th term, and the explicit formula.
Margaret [11]
Here we have a geometric progression!

Data:
n (Number of terms) = 8
a_{8} = ? (e<span>ighth term)</span>
<span>r (common ratio) = ?<span> 
a1 (first term)</span><span> = - 1
a2 second term) = - 4

If: </span></span>r =  \frac{ a_{2} }{ a_{1} } =  \frac{-4}{-1} \to\:\boxed{r= 4}

<span>Now, find the geometric progression
</span>Formula:
a_{n} =  a_{1} *r^{n-1}

Solving:
a_{n} = a_{1} *r^{n-1}
a_{8} = -1 *4^{8-1}
a_{8} = -1 *4^{7}
a_{8} = -1 *16384
\boxed{\boxed{a_{8} = -16384}}\end{array}}\qquad\quad\checkmark
