Given the geometric sequence where a1=1 and the common ratio is 6, what is the domain for n?​
kari74 [83]

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 a_n=a_1(r)^{n-1}, where,

a_n = nth term of sequence,

a_1 = 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:

a_n=1\cdot (7)^{n-1}

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 n\geq 1.

The measure of an interior angle of a regular polygon is 140°140°. find the number of sides of the polygon.
MA_775_DIABLO [31]
\alpha = \cfrac{180(n-2)}{n}  \ \ \ \ \  [ \alpha =interior \ angle, \ \ n=number \ of &#10; \ sides]  \\  \\  \\ 140 = \cfrac{180(n-2)}{n} \\ \\  140n = 180(n-2) \\ \\ 140n=180n-360 \\ \\ 40n=360 \\ \\ n= \frac{360}{40}=9 \ \ sides
