How do you solve this difficult word problem involving terms?

Question

Automobile average cost in '92 was $19,249. Since then, the average increased at $1,136 yearly. What's the general term for the arithmetic sequence modeling automobile costs, where n=1 corresponds to 1992

I will discuss that with my teacher but how would it be solved if there was an end so that I'll at least understand how the problem is solved? please help :)

Answer 1

You need an ending point to that problem to answer it, as well as the formula for growth/decay

Edit: I actually think that can be done with Summations now. Growth/Decay wouldn't work here though. With a summation you can do this without an end.

I havn't done those in a long time though, I might be able to piece it together, but I can't do the layout on the computer. Sorry.

I think it would be Sigma sign (below it would be n=1) above it put the infinity sign. then 19249 + (1136n) to the right of the sigma sign. Sigma looks like this ∑

I'd put that for your answer and go from there.

I don't know what else to tell you lol. That one got me!

Answer 2

while a satellite tv for pc is on the element of earth, so the radius of orbit would be the radius of earth(we call it R) M=mass of the earth m=mass of the satellite tv for pc V=quantity of the earth write the forces in orbit circulate: GMm/R^2=mR(4?^2)/T^2 so: GM(T^2)=4?R^3*?=4/3?R^3*3?=V*3? p=M/V=3?/GT^2 QED!! the estimation: p=3*3.1415/(6.sixty 8*10^-11)(ninety*60)^2=4838... kg/m^3 it is quiet sturdy!! the problem-free of earth density is approximately 5-5.5 .
