Find the next three terms of the sequence 3,9, 27, 81, ...

3

Step-by-step explanation:

divide all numbers right to left by 3 then do that to the next number.

243, 729, 2187 :)

Step-by-step explanation: you can see in this sequence that each term is multiplied by 3 in order to produce the next term. (ex. 3 • 3 = 9) to find the next three terms simply multiply 81 by 3 and it's product by three and so on. Your work would be something like this: (81 • 3 = 243) (243 • 3 = 729) (729 • 3 = 2187).

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.

3

step-by-step explanation:

divide 13.5 by 9 to get the scale factor. it equals 1.5

2 * 1.5 = 3
