What is the fifth term of the geometric sequence 5,15,45,...

Mathematics
1 answer:
denpristay [2]3 years ago

Answer:

405

Step-by-step explanation:

This is a geometric sequence, so we need the common ratio and the first term

To find the common ratio, we take the second term and divide by the first term

15/5 =3

The common ratio is 3

We are multiplying by 3 each time

The first term is 5

The formula is

an = a1 * (r) ^ (n-1)  where n is the term number

We want the 5th term

a5 = 5 * (3) ^ (5-1)

a5 = 5 *3^4

    = 5 *81

    = 405

Answer:

Width = 2x²

Length = 10

Step-by-step explanation:

The greatest common monomial factor of 14x² and 6x² is 2x² so the width is 2x².

Width = 2x²

Length = (14x² ÷ 2x²) + (6x² ÷ 2x²)

            = 7 + 3

             = 10
