Write a recursive sequence that represents the sequence defined by the following explicit formula:
an = 3 – 7(n - 1)

The answer to your question is: 75%.

Step-by-step explanation:

Data

Necklace has 36 blue beads

                        12 white beads

Total number of beads = 48

Process

Use a rule of three

                                  48 beads 100 %

                                  36 beads   x

                                  x = (36 x 100) / 48

                                  x = 3600 / 48

                                 x = 75 % are blue beads
