Answer:
5.8 , which approximately is 6 weeks.
Step-by-step explanation:
the first method is the short one since u just have to double the 85 then divide to 1000.
1000 ÷ ( 85 × 2)
1000 ÷ 170 = 5.882,,,,,. round off to whole number to get 6.
the second method is the addition method.
we start by 85 then keep doubling 85 for every week........inshort.......we add 170 to each weeks number to get the number of followers for the following week.
85 ⇒ 170 ⇒ 340 ⇒ 510 ⇒ 680 ⇒ 850 ⇒ 1020.
1st 2nd 3rd 4th 5th 6th week.
u notice that we add (85×2), 170, to get the following week's number of followers..
in 5 weeks..... the number of followers is yet to get to 1000.
when u divide, u get 5.8.....,and it is not logic to say 5.8823....weeks
since she reaches 1000 followers in the 6th week.......though there is an addition,,,, it is the most appropriate answer.
