Find the first 5 terms of a geometric sequence that starts with -20 and has a growth factor of 0.5

5th of this geomatic sequence are -20, -10, -5, -2.5 and -1.25

Step-by-step explanation:

I. Given geo sequence = output = a , when a is 1st term, r is growth factor and n is term.

Find 1st value, 2nd , 3rd, 4th and 5th

1st term = -20

2nd term = -20 ()

               = -20(0.5)

2nd term = -10

3rd term = -20(0.5)^2 = -5

4th term = -20(0.5)^3 = -2.5

5th term = -20(0.5)^4 = -1.25

You can find any value with this solution, just replace x term in n value.

Hope that help :)

i think it is c, not positive though

step-by-step explanation:

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

=

10

x=5
