Write the explicit formula that represents the geometric sequence-2, 8, -32, 128

maks197457 [2]

Well, since we know is a geometric sequence, we can always get the common ratio of it by simply dividing one value by the one behind it... so let's do so, with say hmm -32 and 8 -32/8 = -4 <-- our common ratio

the first term is -2

$\bf n^{th}\textit{ term of a geometric sequence}\\\\
a_n=a_1\cdot r^{n-1}\qquad 
\begin{cases}
n=n^{th}\ term\\
a_1=\textit{first term's value}\\
r=\textit{common ratio}\\
----------\\
a_1=-2\\
r=-4
\end{cases}\implies a_n=-2(-4)^{n-1}$

What value of (n) makes the equation true ? -2(n)+1.8=3.2 A. -0.7 B. 0.7 C. -3.4 D -2.5

Genrish500 [490]

The answer is A -0.7
-2(n) + 1.8 simplifies to:
-2n + 1.8 = 3.2
- 1.8 -1.8
-2n = 1.4
n = -7
