Use the recursive function for the geometric sequence 2,-6,18 and - 54 to represent the 9th term

f (9) = f (8) • (-3)

f (9) = f (1) • (-3) ^8

f (9) = f (1) + 3 (8)

f (9) = f (8) + 3 (8)

Use the recursive function for the geometric sequence 2,-6,18 and - 54 to represent the 9th term

f (9) = f (8) • (-3)

f (9) = f (1) • (-3) ^8

f (9) = f (1) + 3 (8)

f (9) = f (8) + 3 (8)

Nasir Hebert · Answer 1

A

Step-by-step explanation:

A recursive formula allows the term in a sequence to be obtained from the previous term.

To find any term in the sequence multiply the previous term by the common ratio r

r = - 6 : 2 = 18 : - 6 = - 3

Thus the 9 th term can be found using

f (9) = f (8) * - 3 = - 3f (8) → A

Answer:

f (9) = f (8) • (-3)

Use the recursive function for the geometric sequence 2,-6,18 and - 54 to represent the 9th termf (9) = f (8) • (-3)f (9) = f (1) • (-3) ^8f (9) = f (1) + 3 (8)f (9) = f (8) + 3 (8)

Use the recursive function for the geometric sequence 2,-6,18 and - 54 to represent the 9th term

f (9) = f (8) • (-3)

f (9) = f (1) • (-3) ^8

f (9) = f (1) + 3 (8)

f (9) = f (8) + 3 (8)
