Hello, Since I am having some difficulties with Geometric Series problem, I thought It was kind of nice to post some problems, some which are very challenging, to those interested. The answers I did not post, but if anyone wants them, they can try the questions and are invited to ask me for the answers. Feel free and try these problem, post comments with your answers!!
Ready?
There are Sequence and Series problems! GOOD LUCK!
Find all of the terms of the finite sequence?
1a.
; 1 < n < 5
Find the first five terms and the twelfth term of the infinite sequence.
2a.
Write a formula for the nth term of given the infinite sequence.
3a.
1. Write a formula for the nth term of the geometric sequence 7, 28, 112, 448, .... Do not use a recursive formula.
2. Write a formula for the nth term of the geometric sequence 16, - 4, 1, -1/4, .... Do not use a recursive formula.
3. Find the first term of a geometric sequence with a fifth term of 32 and a common ratio of -2.
4. Find the common ratio for a geometric sequence with a first term of 3/4 and a third term of 27/16.
5. Find the sum of the finite geometric series 3 - 6 + 12 - 24 + 48 - 96.
6. Write a formula for the nth term of the given geometric sequence. Do not use a recursive formula.
