ANSWER
EXPLANATION
The given geometric sequence is
400, 200, 100...
The first term is
The common ratio is
The nth term is
We substitute the known values to get;
The answer is
(0, 5)
(1, 3)
It diverges; it does not have a sum. the sum of a geometric series is given by a /(1-r) where a is the first term and the r is the ratio between the terms. r=3 in the series you have given . The absolute value of r must be less then 1 for a geometric series to converge.
1 whole???i’m not smart lol
we should save money to help others in need. i believe this because there are smart homeless kids out there who want and need an education. honestly do you want to be the person who gets a homeless person hooked on drugs because they don't have an education. and there are people with houses but they don't have the kind of money for college and if they do not get that scholarship. their life can take a turn for the worst. as for research 82% of people get hooked up on drugs because they lose their education an can not get a job. this can also lead to depression. that is one of strongest inside damage. it is worse than anxiety thats pretty bad. And it is also how people end up on the streets. And also giving money means study supplies and if thy study their education will most likely get better!!
