The explicit form of the sequence is an = 100n - 100
<h3>What is Recursive functions?</h3>
Given the recursive functions as;
an = an−1+100
Sequence: 0,100,200,300,…
first term (a) = -0
Common difference of the A.P.
(d) = 100- 0 = 100
The explicit form of the sequence is
an = a + (n-1)d
an = 0 + (n-1)(100)
an = 0 + 100n -100
an = 100n - 100
Hence the explicit form of the sequence is an = 100n - 100

Answer:
1.
-3|2x+6|=-12
|2x+6|=4
2x+6=4
2x+6=-4
x1=-5, x2=-1
2.
|x-2|+10=12
|x-2|=12-10
|x-2|=2
x-2=2
x-2=-2
x1=0, x2=4
When the balloon is on the ground, it is at point 0. It starts to go up at 5 f/m for a time of 4 minutes. So we will multiply 5 by 4 to get 20. At this point, the balloon is 20 feet off the ground. However, we now know that the balloon descends at 2 f/m at a time of 7 minutes. So we must multiply 2 by 7 to get 14. So we know it was at 20, and then it went down by 14.
20 - 14 = 6 feet
This means that the balloon is now 6 feet above the ground.
I hope I've helped! :)
Answer: 350
Step-by-step explanation:
25 percent of 280 is 70 so it is 350
