1. Start at 8 3/9 and count back in steps of 1/9. if the mentioned mixed number is the first number in the sequence, what is the ninth number?
Jawab:
7 4/9Penjelasan dengan langkah-langkah:
First number in the sequence: U₁ = 8 3/9
Steps: d = –1/9 (backward)
The 9th number:
U₉ = U₁ + 8d
U₉ = 8 3/9 + 8(–1/9)
= 8 3/9 – 8/9
U₉ = 7 4/9
∴ The ninth number in the sequence is 7 4/9.

5. What is the sequence of events in the story?
Apa urutan kejadian dalam cerita?
6. 1. What is the name the text?2. Can you tell who was involved, what happened, and what sequence in the text?3. Can you describe the events that happened in the text? 4. What about the closure? please explain.
1. It's recount text because it shares the writer's experience
2. The ones who were involved are the character 'I' and Fanny as the main character, and the tour agency as the minor character. The main idea of the text is about finding the free coupon for holiday out of the blue, it's in the second paragraph
3. The events are the character 'I' just woke up and got a call from Fanny to go out in the afternoon (the introduction) , they found the free coupon with the same exact (the main story) and they exchanged the coupon and went on holiday there (the resolution)
4. The closure is when the main character decided to take the coupon and went on holiday to that destination mentioned. Analysis: The story is too simple in plot with predictable ending and the coincidence (kebetulan) plays the important part of the story.
7. The next terms of the sequence 1,5,11,19....is.....
The question is about Un.
b = U2 - U1 = 5 - 1 = 4
b = U3 - U2 = 11 - 5 = 6
b = U4 - U3 = 19 - 11 = 8
Setiap jaraknya +2
Untuk mencari U5, U6 dan U7 menggunakan rumus Un.
Un = a + (n - 1) b
U5 = 1 + 4b
U5 = 1 + 4(7)
U5 = 29
U6 = 1 + 5b
U6 = 1 + 5(8)
U6 = 41
U7 = 1 + 6b
U7 = 1 + 6(9)
U7 = 55
Deretnya adalah
1,5,9,11,19,29,41,55.

8. 1,17,98,354,.... what will be the next number in the series?

4 9 16 <akar kuadrat dari jarak antar bilangan
(1) 4 9 16
3 5 7 <jarak akar kuadrat
*jarak akar kuadrat merupakan bilangan ganjil
(3),5,7,9<>4,9,16,25
25x25=625
354+625=979
9. The formula of n-term from a number sequence is Un = 1/2 n (n − 3). The 8th term is ...
Jawab:
U8 = 20
Penjelasan dengan langkah-langkah:
The 8th means we replace the n = 8
U8 = 1/2 (8) (8-3)
U8 = (4) (5)
U8 = 20
hope this helpful, thank youu~

Jawaban:
30,28,25,21,16,...,...,-5

Jawaban:
Penjelasan dengan langkah-langkah:
Pennies = 6
Nickels = 9
Dimes = 12
Number of Nickels = 9
Number of the total coins = 6+9+12 = 27
—Find the simplest form of ratio between number of Nickels and number of the total coins.
= 9 : 27
= (9:9) : (27:9)
= 1 : 3 The answer is D
