Answer:

  y+4 = 3(x -1)

Step-by-step explanation:

You are given two points, so you only need to find the slope. The slope is given by the formula ...

  m = (y2 -y1)/(x2 -x1)

  m = (2 -(-4))/(3 -1) = 6/2 = 3

The point-slope equation for a line is ...

  y -k = m(x -h) . . . . . . line with slope m through point (h, k)

Using the first point, the equation is ...

  y+4 = 3(x -1)

What is a formula for the nth term of the given sequence?
lakkis [162]

Answer: option D is the correct answer.

Step-by-step explanation:

The given sequence is a geometric sequence because the consecutive terms differ by a common ratio.

The formula for determining the nth term of a geometric progression is expressed as

an = a1r^(n - 1)

Where

a1 represents the first term of the sequence.

r represents the common ratio.

n represents the number of terms.

From the information given,

a1 = 36

r = 12/36 = 4/12 = 1/3

Therefore, the formula for the nth term of the sequence is

an = 36 × 1/3^(n - 1)

an = 36 × 3^-1(n - 1)

an = 36 × 3^(-n + 1)

an = 36 × 3^(1 - n)
