Answer:

Step-by-step explanation:

The n th term of a geometric sequence is

$a_{n}$ = a₁ $r^{n-1}$

where a₁ is the first term and r the common ratio

Here a₁ = 400 and r = 0.5 , thus

$a_{5}$ = 400 × $(0.5)^{4}$ = 400 × 0.0625 = 25

Answer:

Y = 40

Step-by-step explanation:

First, find the slope-intercept of the table

Slope-intercept form: y = mx + b

$m=\frac{y_2-y_1}{x_2-x_1}$

(3, 1) and (6,2)

$m=\frac{y_2-y_1}{x_2-x_1}\\\\m=\frac{2-1}{6-3}\\\\m=\frac{1}{3}$

$y=mx+b$

$y=\frac{1}{3}x+b$

Find b using (6,2):

$y=\frac{1}{3}x+b\\\\2=\frac{1}{3}(6)+b\\\\2=\frac{6}{3}+b\\\\2=2+b\\\\-2\ -2\\\\0=b$

$y=\frac{1}{3}x+b== > y=\frac{1}{3}x+0== > y=\frac{1}{3}x$

$y=\frac{1}{3}x$

What will be the value of Y when X = 120?

Substitute 120 for x into $y=\frac{1}{3}x$

$y=\frac{1}{3}x\\\\y=\frac{1}{3}(120)\\\\y=\frac{120}{3}\\\\y=40$

(120, 40)

Therefore, when X = 120, Y = 40

Hope this helps!
