Question

Match the sequence (term) with the correct type of sequence (definition).

Match Term Definition
2, 4, 6, 8, ... A) Geometric, common ratio is 2
28, 24, 20, 16, ... B) Geometric, common ratio is 0.5
2, 4, 8, 16, ... C) Arithmetic, common difference is -4
48, 24, 12, 6, ... D) Arithmetic, common difference is 2

Answer 1

2, 4, 6, 8 is A or D which one?

Answer 2

2, 4, 6, 8, ...
is arithmetic because every time add +2

Answer 3

Okay what about the others?

Answer 4

2, 4, 8, 16, ... is geometric
because every time multiplied by 2

Answer 5

okay

Answer 6

after the last ones i have another question

Answer 7

28, 24, 20, 16, ... is arithmetic because every time add by -4

Answer 8

so the answer is ?

Answer 9

E.J. has shown that a function, f(x), grows by 12% for every unit in the domain. What does this prove?

The function f(x) is an arithmetic sequence.

The function f(x) is a geometric sequence.

The function f(x) is not a sequence.

This does not prove anything.

Answer 10

48, 24, 12, 6, ... is geometric ,ratio is 1/2

Answer 11

okay

Answer 12

E.J. has shown that a function, f(x), grows by 12% for every unit in the domain. What does this prove?

The function f(x) is an arithmetic sequence.

The function f(x) is a geometric sequence.

The function f(x) is not a sequence.

This does not prove anything.

Answer 13

this is the last one

Answer 14

The function f(x) is an arithmetic sequence
when
a(n)=a1+(n-1)d
it is linear relation (like a line)

Answer 15

Yes, i think

Answer 16

The function f(x) is an geometric sequence
when
a(n)= a1* q^(n-1)

Answer 17

So the answer is B

Answer 18

I think no one of them is correct ,
may be you type mistake!

Answer 19

I copyed it and pasted

Answer 20

copied

Answer 21

2, 4, 6, 8, ... A) Geometric, common ratio is 2 arithmetic +2
28, 24, 20, 16, ... B) Geometric, common ratio is 0.5 arithmetic -4
2, 4, 8, 16, ... C) Arithmetic, common difference is -4 geometric +2
48, 24, 12, 6, ... D) Arithmetic, common difference is 2 geometric 1/2

Answer 22

E.J. has shown that a function, f(x), grows by 12% for every unit in the domain. What does this prove?

The function f(x) is an arithmetic sequence.

The function f(x) is a geometric sequence.

The function f(x) is not a sequence.

This does not prove anything.

(I need help with this now sir)

Answer 23

a
a+12/100 a = (1.12)a
(1.12)a +12/100 (1.12)a=(1.12)a (1+.12) = (1.12)^2 a
(1.12)^2 a +12/100 (1.12)^2 a= (1.12)^3 a
...
for n times
(1.12)^n a
