Solve for m pls? I'd seriously appreciate it!

Vilka [71]

Answer:

$m=-1$

Step-by-step explanation:

Start by multiplying both sides by 2, this will get rid of the fraction on the left side and will result in the equation $12m+6=2m-4$

Then, subtract 2m from both sides, which leaves the equation as $10m+6=-4$

Then, subtract 6 from both sides, this results with the equation $10m=-10$

Finally, divide both sides by 10, this will result in m=-1

ASAP math help algebra plzzz

skelet666 [1.2K]

This is a geometric sequence because each term is a constant multiple, called the common ratio, of the previous term. In this case the common ratio, noted as "r", is:

8/-2=-32/8=128/-32=r=-4

The first term is -2

Any geometric sequence can be expressed as:

a(n)=ar^(n-1), a=initial term, r=common ratio, n=term number.

Since we know r and a for this problem already we can say:

a(n)=-2(-4)^(n-1)
