Question

graph the arithmetic sequence an=10,6,2,-2,-6....

Answer 1

what do u mean by graphing an equation?

Answer 2

graph what? :D

Answer 3

as far as i know its an arithmetic progression with first element as 10 and common difference -4

Answer 4

there is no equation. it's just graphing the sequence

Answer 5

graphing afew points? :P

Answer 6

i think u r right @mhmdrz91 as the graph would be a straight line few are enuf

Answer 7

the statement \(a_n=10,6,2,-2,-6,..\) makes no sense
what i assume it means is
\[a_1=10,a_2=6,a_3=2,a_4=-2,a_5=-6...\]

Answer 8

yeah, that is what it is but how would i graph the numbers?

Answer 9

the question doesn't really say that i need to do this and that, it just says that i need to graph the sequence.

Answer 10

plot the points \((1,10), (2,6), (3,2), \) etc

Answer 11

why is it (1,10), (2,6), (3,2) ?

Answer 12

the first term is numbered 1 and its value is 10
the second term is numbered 2 and its value is 6
like wise the 3rd term is numbered 3 and its value is 2
term numbers indicate x and its values indicate y
so a coordinate pair ( x, y) will be ( number, value)

Answer 13

the first coordinate is the subscript
\[a_n\] is like
\[f(n)\]

Answer 14

so if \(f(1)=10\) you plot \((1,10)\)

Answer 15

a_1=10,a_2=6,a_3=2,a_4=-2,a_5=-6...would it be (1,10) because of the a_1?

Answer 16

alright i get it then. so i just plot it in for now?

Answer 17

yes in that perspective of yours

Answer 18

yes

Answer 19

thank you

Answer 20

but ummmm... for the geometric sequence would it be the same way?
would i just plot out the points like i did to the arithmetic?

Answer 21

yes the same way
