Answer 1

Answer:

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.

-5+x/3=-11

Answers

add 5 to both sides
5-5+x/3=5-11
0+x/3=-6
x/3=-6
times both sides by 3
3x/3=-18
x=-18

Find the difference of 5063 and 3987 to the nearest thousand

Answers

"difference" means subtract so... 5063 - 3987 = 1076. Now since the question says get it to the nearest thousand it should be 1000. which is your answer.
