Lets analyse, the sequence adds 20 to the previous term, so that is:
f(n + 1) = 20 + f(n)
where f(1) = 110
Answer: 8(x-4) 8 was the common term. So just pull out the 8.
90 minutes = 1.5 hours.
Divide total miles driven by the time to find how many miles are driven in 1 hour:
250 miles / 1.5 hours = 166 2/3 miles per hour.
Multiply the miles driven in one hour by 6 hours:
166 2/3 x 6 = 1000 miles
The answer is 3.83 because you divide 11.49 into 3 packages
