You have to use PEMDAS

$Parentheses \\ Exponents \\ Multiplication \\ Division \\ Addition \\ Subtraction$

You have to do the division and multiplication first.

$3 \times 5 = 15 \\ 20 \div 4 = 5$

The new equation is:

$8+15-5$

First do the addition in the beginning:

$15 + 8 = 23$

At last, subtract 5

$23 - 5 = 18$

Your answer is 18

Answer: (C) 13,120

<u>Step-by-step explanation:</u>

Given the sequence {4, 12, 36, 108, ... , 8748} we know that the first term (a) is 4 and the ratio (r) is $\dfrac{12}{4}=3$

Input the values above into the Sum formula:

$S_n=\dfrac{a(1-r^n)}{1-r}\\\\S_8=\dfrac{4(1-3^8)}{1-3}\\\\.\quad=\dfrac{4(1-6561)}{-2}\\\\.\quad=\dfrac{4(-6560)}{-2}\\\\.\quad=-2(-6560)\\\\.\quad=13,120$
