Answer: f(5) = 16

Step-by-step explanation:

f(n) = (2n + 3)2 – 2n

f(5) = ((2 x 5) + 3)2 – 2 x 5

f(5) = (10 + 3)2 – 10

f(5) = (13)2 – 10

f(5) = 26 – 10

f(5) = 16

Solve 10 X + 8 / 2 X + 7 is equal to 4

ale4655 [162]

Answer:

x = 10

Step-by-step explanation:

$\frac{10x + 8}{2x + 7} = 4$

or, 10x + 8 = 4(2x + 7)

or, 10x + 8 = 8x + 28

or, 10x - 8x = 28 -8

or, 2x = 20

or, x = 20/2

or, x = 10

x = 10

Answer:

The common ratio is 4

Step-by-step explanation:

We need to divide a term by the previous term to find the common ratio in a geometric sequence:

64 ÷ 16 = 4

256 ÷ 64 = 4

By doing it twice we can confirm that the common ratio is 4
