Intergers Help And Awnser Please, list the next three integers in each pattern?

Question

List The next three integers in each pattern
Also for numbers 1 and 2 can you please describe the rules for how you got A and B
1.
a) -4, -1, 2, 5, 8
b) 6, -1, -8, -15, -22

2.
a) -4, 8, -16, 32, -64
b) 2187, -729, 243, -81

3. Describe how to find the next number in each pattern.
a) 2, -5, -12, -19
b) -7, -3, 1, 5
c) -623, 125, -25, 5
d) 3, -12, 48, -192

Answer 1

1. a) -4, -1, 2, 5, 8 ... 11, 14, 17 (each number is 3 more than the previous one)

b) 6, -1, -8, -15, -22 ... -29, -36, -43 (each number is 7 less than the previous one)

2. a) -4, 8, -16, 32, -64 ... 128, - 256, 512 (these are all powers of 2 with each number being double the previous one, with an alternation of signs, first a negative number, then a positive number. Multiply each number by -2 to generate the next)

b) 2187, -729, 243, -81 ... 27, -9, 3

These are all powers of 3 in descending order with each number being one third of the previous one, with an alternation of signs, first a positive number, then a negative number. Divide each number by -3 to generate the next)

3. Describe how to find the next number in each pattern.

a) 2, -5, -12, -19
(each number is 7 less than the previous one)

b) -7, -3, 1, 5
(add 4 to each number to generate the next)

c) -623, 125, -25, 5
(You must mean 625 not 623. These are all powers of 5 in descending order, with alternation of signs. Divide each number by -5 to generate the next)

d) 3, -12, 48, -192
(Multiply each number by -4 to generate the next)

Answer 2

1.
a) -4, -1, 2, 5, 8 = then 11, it's going up by 3 each time.
b) 6, -1, -8, -15, -22 = -29, it's going down by 7 each time.

2.
a) -4, 8, -16, 32, -64 =256, it's being multiplied by -4 each time.
b) 2187, -729, 243, -81 = 9, it's dividing by -9 each time.

3. Describe how to find the next number in each pattern.
a) 2, -5, -12, -19 = -26, it's going down by 7 each time.
b) -7, -3, 1, 5 = 9, it's going up by 4 each time.
c) -623, 125, -25, 5 = -1, it's diving by negative 5 each time.
d) 3, -12, 48, -192 = 768, it's multiplying by negative 4 each time.

hehe did i earn a best answer?

Answer 3

= 4 + 5 + 9 = 18

Answer 4

1. (a) add 3 to the previous integer to get the next one.
11, 14, 17
(b) subtract 7 from the previous integer
-29, -36, -43

2. (a) to get the next answer is multiply the previous number by negative 2
128, -256, 512
(b) divide the previous number by negative 3.
27, -9, 3

3. (a) subtract 7 from the previous number.
(b) add 4 to the previous number.
(c) currently there is no possible answer, but i think you meant that the first number is -625. in that case, just divide the previous number by negative 5.
(d) multiply the previous number by negative 4

Answer 5

1a) 11, 14, 17 add three to the previous number
1b) -29, -36, -43 subtract 7 from the previous number

2a) 128, -256, 512 multiply previous number by -2
2b) 27, -9, 3 divide previous number by -3

3a) -26, -33, -40 same sa 1b
3b) 9, 13, 17 add four to previous number
3c) I think the first number should be -625, if so, next three would be -1, 1/5, -1/25 divide by -5
3d) 768, -3072, 12,288 multiply previous number by -4

Answer 6

1. a) Add 3 to the previous number
11,14,17

b) Subtract 7 from the previous number
-29,-36,-43

2)a) Multiply previous number by -2

128, -256, 512
b) Divide by -3

27,-9,3

3) a)Subtract 7 from previous number
b) Add 4 to previous number
c) The first term should be -625

Divide by -5

d) Multiply by -4

Answer 7

1a x(n+1)=x(n)+3
b x(n+1)=x(n)-7

2a x(n+1)=x(n)*(-2)
b x(n+1)=x(n)/-3

3a x(n+1)=x(n)-7
b x(n+1)=x(n)+4
c x(n+1)=x(n)/(-5) wrong typing at-623 should be 625 i guess
d x(n+1)=x(n)*4

caluculate the rows as far as you need.

Answer 8

1.
a) 11
b) -29

2.
a) 128
b) 27

3.
a) -26
b) 9
c) -1 (I have assumed that the series should start with -625, not -623)
d) 768

Answer 9

4, -12, 36, -108
