Write an explicit rule for the geometric sequence (answers down below) :
den301095 [7]

Answer:

Correct answer is third from the top an = 27 · (1/3)∧(n-1)

Step-by-step explanation:

Given geometric sequence :  27, 9, 3, 1,....

First term a1= 27, second term a2= 9, third term a3= 3 etc...

Standard form of the n-th term is

an = a1 · q∧(n-1)

We will find quotient when we divide second term with first and third with second

q = a2/a1 = a3/a2 = 9/27 = 3/9 = 1/3

Formula fot n-th term is

an = 27 · (1/3)∧(n-1)

God with you!!!

LiRa [457]
Emily Dickinson's poetry was rescued for posterity by her sister (c). Emily Dickinson lived during the American Civil War, but she lived in her father's house in Amherst, Massachusetts. This area was not affected by the Civil War. She was fairly isolated as a poet and, as a result, the events of the Civil War did not play a major role in her poetry. She wrote mainly about the events in her direct environment, with no direct sense of the time in which she lived. Her world consisted of her own home and the surrounding countryside.
