What is the 4th term in the sequence?

The 4th term in the sequence is 7.

Step-by-step explanation:

Assuming

The 1st term of the sequence is

the 2nd term is

the 3rd term is

and the 4th term is

entering that problem on the tube might get you an answer

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
