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 weekinshortwe 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 5.8823weeks

since she reaches 1000 followers in the 6th weekthough there is an addition it is the most appropriate answer.

b. x + 1
