Last year, 150 cases were reported of a new infectious disease. It has been predicted that the number will double every year. How many cases will be reported in the ninth year?

76800 cases

Step-by-step explanation:

The number of cases of new infectious diseases reported last year = 150 cases

Number of cases are going to be double every year

Number of the cases in next or first year=150+150=300

Number of the cases in next or second year=300+300=600

Number of the cases in next or third year=600+600=1200

Number of the cases in next or fourth year=1200+1200=2400

Number of the cases in next or fifth year=2400+2400=4800

Number of the cases in next or sixth year=4800+4800=9600

Number of the cases in next or seventh year=9600+9600=19200

Number of the cases in next or eight year=19200+19200=38400

Number of the cases in next or ninth year=38400+38400=76800

Hence, the total number of cases are 76800 cases

38,400
