Comment on the working

It often works well to use the average value when working consecutive integer problems. The average of an odd number of consecutive integers is the middle one. The average of an even number of consecutive integers is halfway between the middle two.

Answer: a

−

Step-by-step explanation:

Multiply everything by 3 to cancel out the division by 3 on the left, and that should leave you with

−

(Dividing and multiplying are opposites, like adding and subtracting or integrating and differentiating. One does something, the other undoes it. If you want to get rid of a multiplication, divide it. If you want to get rid of an integration, differentiate it.)

9,3,1, 1/3, 1/9........ i need three numbers in the pattern and i dont get it...

SashulF [63]

The pattern is that you are dividing by 3.

Therefore, to work out the next three numbers, you need to divide the last number by 3.

So you'd do:

1/9 ÷ 3 = 1/27

1/27 ÷ 3 = 1/81

1/81 ÷ 3 = 1/243

Therefore, the next three numbers are 1/27, 1/81, and 1/243.
