What term is 1/1024 in the geometric sequence,-1,1/4,-1/

Step-by-step explanation:

The explicit formula for a geometric sequence:

- n-th term

- first term

- common ratio

We have

The common ratio:

If then the common ratio is

Put to the explicit formula:

Put and solve for n :

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204

3+x
