Answer:

aₙ = 40*(1/2)ⁿ⁻¹

Step-by-step explanation:

<u>As per graph we have:</u>

  • a₁ = 40, a₂ = 20, a₃ = 10, a₄ = 5, a₅ = 2.5

<u>So the first term is </u><u>40</u><u> and common ratio is </u>

  • 20/40= 10/20 = 5/10 = 2.5/5 = 1/2

<u>Formula for nth term is:</u>

  • aₙ = a₁rⁿ⁻¹
  • aₙ = 40*(1/2)ⁿ⁻¹

sergey [27]

Answer: 2, 2, 2, 5, 13, 13.

Step-by-step explanation:

845 ÷ 5 = 169

169 ÷ 13 = 13

13 ÷ 13 = 1

What is the equation of the line that is
Lena [83]

Answer:

y = 1x - 3

Step-by-step explanation:

Note that the given line has slope +1.

Any line parallel to this line must also have slope +1.

Apply the slope-intercept form y = mx + b:

Inserting -3 for y, 0 for x and 1 for m, we get the y-intercept

-3 = 1(0) + b, which tells us that b = -3 and that the desired equation is

y = 1x - 3
