Aculture started with 6,000 bacteria. after 6
hours, it grew to 7,200 bacteria. predict how
many bacteria will be present after 17 hours.
round your answer to the nearest whole
number.

20400

Step-by-step explanation: You divide 7200 by 6 (hours) and you get 1200 ( which is the number of how much bacteria grew per hour) and then you multiply by the number of hours you want to predict the bacteria will grow (17 hours) and you get 20400 or 20,400 whatever it’s the same

an = 22 + (n-1) *6

110 seats

step-by-step explanation:

an=a1+(n-1)(d)

a1 = 22   this is the first item in the sequence

d =6   this is how the sequence goes up

a)   an = 22 + (n-1) *6

b) a12 = 22 + (12-1) *6

    a12 = 22+11*6

  a12 = 22 +88

  a12 = 110
