Enter a recursive rule for the geometric sequence. 6, −18, 54, −162, ...
1 answer:
Answer:
The required recursive formula is:
Step-by-step explanation:
We are given a geometric sequence as:
6,-18,54,-162,.....
Clearly after looking at different terms of the sequence we could observe that the sequence is an geometric progression (G.P.) with common ratio= -3 denoted by r.
Let represents the nth term of the sequence.
This means that:
As the common ratio is -3.
so,
Hence, the required recursive formula for the geometric sequence is:

The Probability found is:
P =
Step-by-step explanation:
Let x be the 10 cents coin.
Let y be the 25 cents coin.
We have to find all the possible outcomes
1) First coin = 10 cents, Second coin = 10 cents , so
(x,x) = 20
2) First coin = 10 cents, Second coin = 25 cents , so
(x,y) = 35
3) First coin = 25 cents, Second coin = 10 cents , so
(y,x) = 35
4) First coin = 25 cents, Second coin = 25 cents , so
(y,y) = 50
Find the probability of each outcome:
P(x,x) =
P(x,y) =
P(y,x) =
P(y,y) =
Add all the probabilities where sum is at least 35 i.e P(x,y) , P(y,x) , P(y,y)
P(x,y) + P(y,x) + P(y,y) =

For this case, we must find the quotient by dividing the polynomial . We must build a quotient that, when multiplied by the divisor, eliminates the terms of the dividend until it reaches the rest, as shown in the attached figure. At the end of the division, to verify we must bear in mind that:
