Maria spent $35 to fill 15 gallons
of gas in her car.
How much does
6 gallons of gas
cost?

$ 14

Step-by-step explanation:

35 divided by 15 is 2.3333333 times that by 6 to get 14.

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.
