Answer #1

Find the fifth term of the geometric sequence 6?, 2?, 2/3...

1) Given the geometric sequence an with the
following information, find a10.
a5=15
a8=59
Select the correct answer below:
a10=5/27
a10=5/9
a10=5/81
a10=5/243
2)
Is the following sequence a geometric sequence? If so, find its
common ratio.
11,−112,−6,−132,−7,…
Select the correct answer below:
The sequence is geometric with common ratio −3/32.
The sequence is geometric with common ratio −1.
The sequence is geometric with common ratio −1/2.
The sequence is geometric with common ratio −1/4.
The sequence is not geometric.

1a. Find a1 and r for a geometric sequence with the values given
below
an= 63, n=3, Sn=91
a1= ?
r=?
b. find the sum of the terms in the arithmetic sequence below
Sn
-10, -12, -14, -16,... -24
Sn=?

the frequency sequence representation for the time sequence
[3,4,1,-2] is {2,2-j6,2.2+j6}
is
this true or false

How can you determine if a sequence is arithmetic, geometric, or
neither? Give an example of each type of sequence.

Determine whether the Mean Value Theorem can be applied to ?(?)
= ?^3 − 3? + 2 on the closed interval [−2,2].
If the Mean Value Theorem can be applied, find all values of ??
in the open interval (−2,2) such that
?′ (?) = ?(2) − ?(−2) /2 − (−2)
If the Mean Value Theorem cannot be applied, explain why
not.

1. Consider the geometric series −1/4+3/16−9/64+27/256+... Use
summation notation to write this series and determine whether it
converges. If it does, find the sum.

The 4th,5th and the 6th terms of geometric sequence
are X-4, X +2 and 3X I+1
# find the value of the first term if X<0(ie X is
negetive?)
*the first term of the arithmetic sequence is 10 and
the 6th term is 85find the first 3terns of the sequence

1a. Find any of the values a1, r, an, n, or sn that are missing
from the geometric sequence
r= 5/2, n=4, S4=1624
the value of a1 is?
b. find the sum of the first n terms of the indicated geometric
sequence with the given values
1/8 + 1/2 + 2 + (X) times (X) times (X)times + 32
