What is a formula for the nth term of the given sequence? 250, 100, 40...​

The formula for the nth term of the sequence is

Step-by-step explanation:

Geometric sequence:

In a geometric sequence, the quotient of consecutive terms is always the same, called common ratio.

The equation is given by:

In which is the first term and r is the common ratio.

250, 100, 40

First term is 250, so

Common ratio is

So

The formula for the nth term of the sequence is

the answer to the question is a

step-by-step explanation:

it has the same slope and the same y-intercept.

y + 11 = -7/9(x - 18)

y + 11 =-7/9x + 14

b

y = -7/9x + 3

y-intercept (0, 3)

.632

step-by-step explanation:

6 * 1/10 = 3/5

3*0.01 = 0.03

3/5 + 0.03 = .63

2*0.002 = .002

.63 + 0.002 = .632
