Write an explicit formula for a_na

Masja [62]

Explicit formula for the sequence 29,20,11....... is $a_n=38-9n$

Given :

term of the sequence 29, 20, 11, ...

We need to find out the formula for the nth term of the given sequence

Lets find out whether the given sequence is arithmetic or geometric

In the given sequence , common difference is 9

$20-29=-9\\11-20=-9$

we can say difference =-9

General explicit formula

$a_n=a_1+(n-1)d$

where a1 is the first term

common difference d=-9

substitute the values

$a_n=a_1+(n-1)d\\a_n=29+(n-1)(-9)\\a_n=29-9n+9\\a_n=38-9n$

Explicit formula for the sequence 29,20,11....... is $a_n=38-9n$

We’ll use probability to answer this question.

Probability: Number of even numbers / All numbers added together.

Odd numbers: 1,3,7
Even numbers: 4

All numbers added together (amount of numbers not the numbers itself!) = 4

Amount of even numbers = 1

Probability of getting an even number is 1/4

Answer: Yes she is correct, the probability of getting an even number is 1/4.
