Write the explicit formula that represents the geometric sequence -2, 8, -32, 128
MissTica
So hmm the first term is -2

and if we divide one term by the term before it, we'd get the "common ratio" "r"

so hmm say -32/8 that gives us -4, so r = -4

thus \bf n^{th}\textit{ term of a geometric sequence}\\\\
a_n=a_1r^{n-1}\qquad 
\begin{cases}
a_1=\textit{first term}\\
r=\textit{common ratio}\\
----------\\
a_1=-2\\
r=-4
\end{cases}\implies a_n=-2(-4)^{n-1}

What is 2x-3y=7 please help thanks
Dennis_Churaev [7]
Simplifying -2x + -3y = -7

Solving -2x + -3y = -7

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '3y' to each side of the equation. -2x + -3y + 3y = -7 + 3y

Combine like terms: -3y + 3y = 0 -2x + 0 = -7 + 3y -2x = -7 + 3y

Divide each side by '-2'. x = 3.5 + -1.5y Simplifying x = 3.5 + -1.5y
