Answer:

a = $\frac{r-q}{g}$

Step-by-step explanation:

Given

ga + q = r ( subtract q from both sides )

ga = r - q ( isolate a by dividing both sides by g )

a = $\frac{r-q}{g}$

Answer:

The missing number is 4

Step-by-step explanation:

Given

21 x 39 x _____ x 19 divided by 12 = 5187

Required

Fill in the gap

Let the missing number be represented with y; So, the expression becomes

$\frac{21 * 39 * y * 19 }{12} = 5187$

Multiply both sides by 12

$12 * \frac{21 * 39 * y * 19 }{12} = 5187 * 12$

$21 * 39 * y * 19 = 62244$

Rearrange the expression on the left hand side

$21 * 39 * 19 * y = 62244$

$15561 * y = 62244$

Divide both sides by 15561

$\frac{15561 * y}{15561} = \frac{62244}{15561}$

$y = \frac{62244}{15561}$

$y = 4$

Hence, the missing number is 4

What is the value of the fourth term in a geometric sequence for which a1 = 30 and r = 1/2?.

Mariana [72]

$\bf n^{th}\textit{ term of a geometric sequence}\\\\
a_n=a_1\cdot r^{n-1}\qquad 
\begin{cases}
n=n^{th}\ term\\
a_1=\textit{first term's value}\\
r=\textit{common ratio}\\
----------\\
a_1=30\\
r=\frac{1}{2}\\
n=4
\end{cases}\implies a_4=30\left( \frac{1}{2} \right)^{4-1}$
