Answer:

$a_(n)=12n-8$

Step-by-step explanation:

We have been given a recurrence relation $a_(n+1)=a_(n)+12$ and the first term of the sequence $a_(1)=4$ .

We can rewrite the given recurrence relation as: $a_(n+1)-a_(n)=12$

We know that if difference between two consecutive terms is always constant, the sequence is called an arithmetic sequence. So we are dealing with an arithmetic sequence with first term as 4 and common difference as 12.

We can therefore, write an explicit formula for nth terms of the sequence as.

$a_(n)=a_(1)+(n-1)d\na_(n)=4+(n-1)(12)\na_(n)=4+12n-12\na_(n)=12n-8\n$

This is the required explicit function rule for the given sequence.

johns test grades in his science class are 82, 93, 75, and 89 what is his average? 1. (87.45) 2. (80.00) 3. (90.40) 4. (89.25) 5. (84.75)

Answers

Answer:

The average of the John scores is 84.75.

Step-by-step explanation:

Formula of average is given as :

$A=\frac{\text{Sum of all the terms}}{\text{Number of terms}}$

We have:

Test grades of John: 82, 93, 75, and 89

Number of terms - 4

Average of the score of the John;

$a=(82 + 93 +75 + 89)/(4)=84.75$

The average of the John scores is 84.75.

First you add all the numbers together. So you add 82+93+75+89 to get 339. Once you get that, you divide it by the amount of numbers there are. In this case, it's 4. 339 divided by 4 is 84.75.
