C. 160, 80, 40, 20 2. Write the first five terms of each sequence. Determine whether each sequence is
arithmetic, geometric, or neither.
a. a(1) = 7, a(n) = a(n − 1) – 3 for n > 2.2.4.3
b. b(1) = 2, b(n) = 2 · b(n − 1) - 1 for n > 2.
C. c(1) = 3, c(n) = 10 c(n - 1) for n > 2.
d. d(1) = 1, d(n) = n. d(n − 1) for n 2 2.

b

step-by-step explanation:

ez

dc=6 square root of 3 and ac is 12 square root 3

c and d

step-by-step explanation:

square root of 3/2 = 18/c

cross multiply to get 18*2=√3*c

36/√3 * √3/√3 = c

c= 36*√3/3

c=12√3

this linear equation would have just one solution.

step-by-step explanation:

the reason why this would have one solution is that it is an expression with just one variable. since that variable is not raised to a power, it will always have just one solution.

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

step-by-step explanation:

formula

x = x1 + p/w(x2 - x1)

let the line segment ab with a(x1,y1) and b(x2,y2)

a point(x,y) divide ab in the ratio, 2: 3 the x coordinate can be written as

x = x1 + p/w(x2 - x1)

here p=2 and w = 2+3

therefore,

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

similarly y coordinate y = y1 + 2/5(y2 - y1)
