A Silicon Valley billionaire purchases 3 new cars for his collection at the end of every month. Let an denote the number of cars he has after n months. Let a0 = 23. What is a8 (or how many cars does he have after the end of 8th month)?

47 cars

Explanation:

Data provided in the question:

Number of cars purchased at the end of each month = 3

Initial number of cars i.e a0 = 23

Now,

Number of cars purchased in 8 months

= 8 × Number of cars purchased at the end of each month

= 8 × 3

= 24

Therefore, the total number of cars after the end of 8 months will be

a8 = 23 + 24

or

a8 = 47 cars

the major difference between the two is the objective and the reward of the game. candy crush has a puzzle theme with the objective of meeting a specific quota of points or objects, you are able to gain access to the next level and compete with peers on the process. on duolingo the objective is rather different, you are given sets of questions for you to answer for you to move to the next level and as for the reward, you are able to learn available language as this is an app developed to teach the user about other languages.
