100PTS PLS HURRY I ONLY HAVE 40 MINUTES Determine the common ratio and find the next three terms of the geometric sequence.

hammer [34]

Answer:

$\Large \boxed{\mathrm{\bold{B.} \ -0.5 \ ; \ 0.875 \ , \ -0.4375 \ , \ 0.21875}}$

Step-by-step explanation:

The common ratio can be found by finding the quotient of a term and the previous term in the sequence.

$\displaystyle \frac{3.5}{-7} =-0.5$

The common ratio is -0.5.

The rule is to multiply a term in the sequence by -0.5 to get the next term.

Next 3 terms :

$-1.75 \times -0.5=0.875 \\\\ 0.875 \times -0.5 = -0.4375 \\\\ -0.4375 \times -0.5=0.21875$

The next 3 terms are 0.875, -0.4375, 0.21875.

What is the value of x in the equation ?

zheka24 [161]

Answer:

$x=2$

Step-by-step explanation:

This is our equation

$2.5\left(6x-4\right)=10+4\left(1.5+0.5x\right)$

First off we can distribute the 2.5 and the 4

Now our equation is $15x-10=10+6+2x$

subtract $2x$ from both sides

$13x-10=16$

add $10$ to both sides

$13x=26$

Divide both sides by $13$

$x=2$
