Determine whether each sequence is arithmetic, geometric, or neither. a. a(1) = 7, a(n) = a(n − 1) – 3 for n > 2.
b. b(1) = 2,b(n) = 2 · b(n– 1) - 1 for n 2 2.
<
C. c(1) = 3,c(n) = 10 •c(n-1) for n 2 2.
d. d(1) = 1,d(n) = n. d(n-1)
·d(n − 1) for n > 2.

1/800 is the right answer

5x + 3y = - 4

step-by-step explanation:

the equation of a line in standard form is

ax + by = c ( a is a positive integer and b, c are integers )

express the line first of all in slope- intercept form

y = mx + c ( m is the slope and c the y-intercept )

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (7, - 3) and (x₂, y₂ ) = (4, - 8)

m = = -

y = - x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (4, - 8 ), then

- 8 = - + c ⇒ c = -

y = - x - ← in slope-intercept form

multiply all terms by 3 to eliminate the fractions

3y = - 5x - 4 ( add 5x to both sides )

5x + 3y = - 4 ← in standard form

probably .5

i can on others if necessary.

i agree because i see the other persons thinking is clear
