Question

can someone please help with algebra 2b for connections? i need step by step help..
Consider the infinite geometric series
(picture posted below)

a. Write the first four terms of the series.
b. Does the series diverge or converge?
c. If the series has a sum, find the sum. (3 points)

Answer 1

a.
1. -4(1/3)^(1-1) = -4 x 1 =-4
2. -4(1/3)^(2-1) = -4/3
3. -4(1/3)^(3-1) = -4/9
4. -4(1/3)^(4-1) = -4/27

maybe

Answer 2

oooh ok.. thats kinda what i thought too.. do u know about the other questions?

Answer 3

@quinnisaghost ?

Answer 4

Rewrite the questions pls

Answer 5

a. Write the first four terms of the series.
b. Does the series diverge or converge?
c. If the series has a sum, find the sum.

Answer 6

@quinnisaghost ??

Answer 7

the series converges.
sum= -4/(1-(1/3))=-4/(2/3)=-6

Answer 8

how can you tell if it converges or diverges?

Answer 10

"Usually these two terms describe end behavior. As x approaches positive or negative infinity, if f(x) diverges, then it means that f(x) does not approach a set value. For example, in f(x) = x^2, as x approaches positive or negative infinity, f(x) does not approach a set value (it goes to positive infinity). On the other hand, if f(x) converges, then it means that f(x) does approach a set value. For example, in f(x) = e^x, as x approaches negative infinity, f(x) approaches 0; however, for the same function, as x approaches positive infinity, f(x) diverges."
