Answer:

3 + 6 + 12 + 24 + ⋯ is the corresponding geometric series. The sum of a geometric series can be determined using the formula: = 1( − 1)

Step-by-step explanation:

For any value of x, the sum <br> 3<br> ∑ k(2x-1) <br> k=0<br> is equivalent to
MArishka [77]

The equivalent value of the sum for any value of "x" is 12x - 6

<h3>How to find the sum of functions?</h3>

Given the sum of the expression as:

3

∑ k(2x-1)

k=0

We need to take the sum of the function at the point where k = 0 to 3

3

∑ k(2x-1) = 0(2x-1) + 1(2x - 1) + 2(2x-1) + 3(2x - 1)

k=0

3

∑ k(2x-1) = 2x-1+4x-2+6x-3

k=0

3

∑ k(2x-1) = 12x - 6

k=0

Hence the equivalent value of the sum for any value of "x" is 12x - 6

PLEASE HELP ME! I REALLY NEED HELP!
Nuetrik [128]

This formula means that a(n) for n, when n is the term number, will give you the term. Meaning, we just have to plug in 55 for n.

a(55) = -1 + 3(55 - 1)

a(55) = -1 + 3 * 54

a(55) = -1 + 162

a(55) = 161

If you recall y=mx+b, the slope-intercept form of a linear equation, the slope, m, is the rate of change of the equation, and the y-intercept is b. 

When switching to function notation, we simply swap y for f(x), and if we start at x=0 and graph in the positive x direction, we've started at whatever initial value exists (the y-intercept value).

Simply: F(x) = 2/3 x + 4
