Can you please help me answer this picture

I believe it's

A. b + 2=b + 2

A. It is a geometric sequence.

B.  She will complete station 5 , 64 minutes or 1 hour and 4 minutes after starting.

C. The time she will complete the 8th station is given by,  8 hours and 32 minutes  after starting.

Step-by-step explanation:

The x-coordinate is the station number , and the y co-ordinate is the time in minutes since the start of the race that she completed the task .

The co-ordinates are given as following,

x       y

1        4

2       8

3       16

4       32

Hence, it is given as,

Y = minutes(1)

A. So, it is a geometric sequence.

B. The time required by her to complete station 5 is given by,

   Y =    minutes

      =    minutes

      = 64  minutes

Hence, she will complete station 5 , 64 minutes or 1 hour and 4 minutes after starting.

C. The time she will complete the 8th station is given by,

    Y =  minutes

        =  512 minutes

        =    hours

        =   hours

        = 8 hours 32 minutes  (after starting)
