To find the common and to see whether the sequence is geometric or not you have to divide n+1 term to n term. 

For example 2nd to 1st:
6:2=3
18:6=3

The answer is yes. The sequence is geometric and the common ration is 3. I hope that this is the answer that you were looking for and it has helped you.

A car traveled 88 km in 1 hour, 90 km in the next 2 hours, and then 76 km in 1 hour before reaching its destination. what was th
luda_lava [24]

The formula for Average speed = \frac{Total Distance}{Total Time}

The car travels 80 km in 1 hour.

Then the car travels 90 km in 2 hours.

And finally the car travels 76 km in 1 hour

So the total distance covered by the car = 80 + 90 + 76 = 246 km

The total time taken to cover this distance = 1 + 2 + 1 = 4 hours.

So average speed = \frac{246}{4}= 61.5

The average speed of the car is 61.5 km / h

4x^2-7x=15<br> Solve by factoring and please please please explain or show the work
vodomira [7]

Answer:

x=3 and x=-1.25

Step-by-step explanation:

4x^2-7x=15

subtract 15 from each side:

4x^2-7x-15=0

factor  (trying different numbers that the sum is 7 and the quotient is 15)

(2x-6 )(2x+2.5 )=0

2x-6=0 add 6 to each side

2x=6

x=3

2x+2.5=0   subtract 2.5 from each side

2x=-2.5

x=-1.25
