3) Here is a recursive function for sequence f: f(1)=23,f(n)=f(n−1)−7. The explicit formula for the term is f(n)=23−7(n−1). a. E
BlackZzzverrR [31]

Using the recursive and explicit formula

first three terms are 23,16, 9 and it is same for both . So they have same sequences .

Recursive function can be applied using previous term . So we use Explicit formula to find f(20)

f(20)=-110

Given :

Recursive function for sequence f: f(1)=23,f(n)=f(n−1)−7

explicit formula for the term is f(n)=23−7(n−1).

Lets find out first three terms using both the formulas

Recursive function , Replace n=2,3 to find out second and third terms

f(1)=23,f(n)=f(n-1)-7\\n=2\\ f(2)=f(2-1)-7\\f(2)=f(1)-7=23-7=16\\n=3\\f(3)=f(2)-7=16-7=9

So first three terms are 23,16, 9

Lets do the same using explicit formula but we take n=1,2,3

f(n)=23-7(n-1)\\n=1\\f(1)=23-7(1-1)=23\\f(2)=23-7(2-1)=16\\f(3)=23-7(3-1)=9

First three terms using explicit formula is 23,16,9

From these we can see that  these definitions have same sequence.

Now we find out f(20). To find f(20) we use explicit formula because to use recursive function we need f(19) to find f(20)

Recursive function can be applied using previous term

f(n)=23-7(n-1)\\n=20\\f(20)=23-7(20-1)\\f(20)=-110

The value of f(20)=-110

Find the probability of getting a non prime number if a die is thrown once
Pachacha [2.7K]
<span>The correct answer is 1/3.

Explanation:
If a number is non-prime, that means that it is divisible by more than 1 and itself. The only numbers that this is true for on a die are 4 and 6.

There are two possible outcomes out of a total of 6 outcomes on a die, so the probability is 2/6=1/3.</span>
