Question

Write down the fifth term and the general term of following sequence : 8,4,2,...

Answer 1

Answer:

The terms listed are 8, 4, and 2 in that order. From what we can see, it is a geometric sequence whose next term is gotten by dividing the previous term by 2. The formula for finding the nth term of a  geometric sequence is given as $ar^{n-1}$, where

a = first term which is 8

r = common ratio, 1/2 or 0.5

n = is the term we're looking for, 5

Putting all these together into one solid equation, we have

8 * $0.5^{5-1}$ =

8 * $0.5^{4}$ =

8 * 0.0625 = 0.5

Therefore, the 5th term of the sequence is 0.5. Similar example can be seen here brainly.com/question/9300199
