What is the 15th term in the sequence using the given formula? Cn=3n-1
2 answers:
Answer: The correct option is (C) 44.
Step-by-step explanation: We are given to find the 15-th term of the sequence using the following formula for the n-th term of the sequence:
Since we are to find the 15-th term of the given sequence, so we will substitute the value of n as 15 in the given formula.
Substituting n = 15 in the given formula (i), we get
Thus, the 15-th term of the given sequence is 44.
Option (C) is correct.

Answer:
The change to the face 3 affects the value of P(Odd Number)
Step-by-step explanation:
Analysing the question one statement at a time.
Before the face with 3 is loaded to be twice likely to come up.
The sample space is:
And the probability of each is:
P(Odd Number) is then calculated as:
Take LCM
After the face with 3 is loaded to be twice likely to come up.
The sample space becomes:
The probability of each is:
Take LCM
Comparing P(Odd Number) before and after
--- Before
--- After
<em>We can conclude that the change to the face 3 affects the value of P(Odd Number)</em>
