Each number in a list of numbers can be found using the expression 6 − 23(n − 1), where n is a positive integer that gives the position of the number in the list. What is the thirteenth number in the list? A. −8
B. −2
C. 8
D. 13

Step-by-step explanation:

the answer is 21%.

answer: solve 5\cdot 2^x=2405⋅2  

x

=2405, dot, 2, start superscript, x, end superscript, equals, 240.

solution

to solve for xxx, we must first isolate the exponential part. to do this, divide both sides by 555 as shown below. we do not multiply the 555 and the 222 as this goes against the order of operations!

\begin{aligned} 5\cdot 2^x& =240 2^x& =48 \\ \end{aligned}  

5⋅2  

x
