Question

Please help! how do Arithmetic and geometric sequences become linear and exponential functions? @imqwerty

Answer 1

Your question would be answered if you understood the general formulae for arithmetic and geometric progressions. In turn you would understand the general formulae if you know the definition of what arithmetic and geometric series are...?

Answer 2

Arithmetic sequence \[a _{n}= a _{1}+(n-1)d\]
Geometric sequence \[a _{n}=a _{1}r ^{(n-1)}\]

Answer 3

I don't understand the question

Answer 4

arithmetic sequences are linear
you have written a linear equation above

geometric sequences are exponential
you have written a exponential equation above

Answer 5

I dont understand it either haha.. thats what the question is word for word though

Answer 6

are you asking how to solve the following:
\[a_n=a_{n-1}+d\]

\[a_n=r \cdot a_{n-1}\]

Answer 7

Nope the question was word for word :/ oh well i guess that will do

Answer 8

maybe they want you to write in function notation

Answer 9

I honestly have no idea.. but i have 2 more questions do you mind helping if you can?
