Arithmetic sequence
5,3,1,-1 find a^18

Arithmetic sequence  5, 3, 1, -1 then value of a^18 is 3814697265625.

Solution:

Given, arithmetic sequence is 5, 3, 1, -1

We have to find the value of  

We know that, first term of any A.P is represented by the letter “a”

So, here in our problem first term a = 5

Then we have to find the value of  

Hence, the value of a^18 is 3814697265625.

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.
