a_15 = 90
a_n = 6n
Step-by-step explanation:
Given sequence is:
6, 12, 18, 24,...
First of all we have to find the common difference. The common difference is the difference between consecutive terms of an arithmetic sequence.
Here,
The general form for arithmetic sequence is:
Putting the values for a_1 and d
<u>a) Find a15</u>
<u>b) Write an equation for the nth term.</u>
The equation is: a_n=6n

The value of given expression when m = 3 is 27
<h3><u>Solution:</u></h3>
Given expression is 
We have to evaluate the given expression for m = 3
To find for m is equal to 3, substitute m = 3 in given expression
From given expression,
Plug in m = 3 in above expression
------ eqn 1
We know that,
can be expanded as,
Applying this in eqn 1, we get
Simplify the above expression
Therefore, for m = 3 we get,
Thus value of given expression when m = 3 is found
First you multiply 4*n and n=3 so 4*3 = 12
then you have 9+12-1
9+12= 21
21-1=20
so your answer would be 20
True.
The diameter is the axis of symmetry of a circle.
The diameter divides the circle into two equal parts. Therefore, it can be considered an axis of symmetry. Everything on the right of the diameter is the same as everything on the left of the diameter.
answer
True.
