$\bf (\stackrel{x_1}{x}~,~\stackrel{y_1}{-4})\qquad (\stackrel{x_2}{2}~,~\stackrel{y_2}{8}) \\\\\\ slope = m\implies \cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{8-(-4)}{2-x}=\stackrel{\stackrel{m}{\downarrow }}{-3}\implies \cfrac{8+4}{2-x}=-3 \\\\\\ \cfrac{12}{2-x}=-3\implies 12=(2-x)(-3)\implies 12=-6+3x \\\\\\ 18=3x\implies \cfrac{18}{3}=x\implies 6=x$

In two or more complete sentences, explain whether the sequence is finite or infinite. Describe the pattern in the sequence if i

Ray Of Light [21]

Answer:

Infinite sequence with terms $t_{n+1}=t_n\cdot ab$ or $t_{n+1}=2a\cdot (ab)^n=2a^{n+1}b^n.$

$t_7=2a^7b^6.$

Step-by-step explanation:

Consider the pattern

$2a,\ 2a^2b,\ 2a^3b^2,\ 2a^4b^3,\ ...$

First term of this pattern is

$t_1=2a,$

second -

$t_2=t_1\cdot ab,$

third -

$t_3=t_2\cdot ab,$

fourth -

$t_4=t_3\cdot ab,$

fifth -

$t_5=t_4\cdot ab=2a^4b^3\cdot ab=2a^5b^4,$

sixth -

$t_6=t_5\cdot ab=2a^5b^4\cdot ab=2a^6b^5,$

seventh -

$t_7=t_6\cdot ab=2a^6b^5\cdot ab=2a^7b^6.$

This equence is infinite and each next term is obtained from the previous multiplying by ab.
