First you need to determine which type of sequence is this. Because the difference between 2 successive numbers is constant and it is equal to 10 this sequence is geometric one.
d = 10
To calculate what is the value of some member of this sequence you use formula:
An = Ao + (n-1)*d
where n represents position of element An, Ao is value of first element in the sequence.
Replacing values we get:
A110 = -7 + 109*10
A110 = 1083.
500 / 2 = 250 miles per hour ( rate of speed)
250 * 8 = 2,000 miles in 8 hours
Answer:
g = 8
Step-by-step explanation:
3g - 6 = 18
<u> +6 +6</u>
3g = 24
divide by 3
g = 8
Answer:
w=3
Step-by-step explanation:
(w+3)x2=4w
2w+6=4w
2w+6-6=4w-6
2w-4w=4w-6-4w
-2w=-6
-2w/2 = -6/2
w=3
