We have been given that a geometric sequence's 1st term is equal to 1 and the common ratio is 6. We are asked to find the domain for n.
We know that a geometric sequence is in form
, where,
= nth term of sequence,
= 1st term of sequence,
r = Common ratio,
n = Number of terms in a sequence.
Upon substituting our given values in geometric sequence formula, we will get:

Our sequence is defined for all integers such that n is greater than or equal to 1.
Therefore, domain for n is all integers, where
.
Answer:
f(5) = 17
Step-by-step explanation:
You just plug in 5 for x:
f(5) = 3(5) + 2
f(5) = 15 +2
f(5) = 17
Hope this helps!

Answer:
y = 11 1/2
Step-by-step explanation:
7y - 63 = y + 3
-y. -7
6y - 63 = 3
+ 63. + 63
6y = 69
/6. /6
y = 11 1/2
Answer:
3/5
Step-by-step explanation:
1/5r + 8/15
~Substitute
1/5(1/3) + 8/15
~Simplify
1/15 + 8/15
~Add
9/15
~Simplify
3/5
