What is the funtion notation of this sequence?: 2.5,7.5,22.5,67.5,202.5?

Step-by-step explanation:

The given sequence : 2.5,7.5,22.5,67.5,202.5

here first term  (a)= 2.5

Second term = 7.5

Third term = 22.5 and so on

The difference between the two consecutive terms is increasing but have common ratio as:

Common ratio (r) =

So this sequence follows geometric progression.

nth term in GP =

Required function notation:

i.e. the function notation of given sequence :  

1     sepan

2     encuentren

3     tenga

4     hable

5   parezca

6   llegue

4 and 5)16.97 or 12√2

6)15.59 or 9√3

7)y = 15.59 or 9√3     x =27

8)17.80
