If the fifth term in a geometric sequence is 1∕27 and the common ratio is 1∕3, find the explicit formula of the sequence. Question 14 options:

A)

an = (1∕3)n – 1 for n ≥ 1

B)

an = (3) ⋅ (3)n – 1 for n ≥ 1

C)

an = (3) ⋅ (1∕3)n – 1 for n ≥ 1

D)

an = (1∕27) ⋅ (1∕3)n – 1 for n ≥ 1

add my sc = bmic ava, no spaces

:) hope i can help bbg/bbb

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make
