The first term of a geometric sequence is 2, and the common ratio is 3. What is the 8th term of the sequence?

The 8th term of the sequence is 4374.

Step-by-step explanation:

It is given that,

The general form of geometric  sequence is a, ar, ar²,ar³,.......

where,

The formula to find the nth term of the geometric sequence is given by :

⇒  

The question is asked to find the 8th term. Hence n = 8.

⇒  

⇒

⇒

⇒

∴ The 8th term of the sequence is 4374.

8(-10x+3.5y-7)

8×-10x + 8×3.5y + 8×-7

-80x + 28y - 56

therefore

-80x+28y-56 is the correct answer

step-by-step explanation:

descending order means to order the polynomials from the term with the largest exponent to the term with the smallest exponent.  

therefore, the correct answer is d.
