Question

write a formula for the apparent nth term of the sequence ( assume that n begins with 1) -2, 2, -2, 2

Answer 1

u have
\[ \large n_1=-2 \]
\[ \large n_2=2=(-1)(-2)=(-1)n_1 \]
\[ \large n_3=-2=(-1)2=(-1)^2n_1 \]

Answer 2

can u do it for \(n_4\) ?

Answer 3

i don't need it for individual answrs i just need the whole formula that works for all of them

Answer 4

i know doing these particular cases will help u figure the general formula out.
it's called inductive reasoning

Answer 5

well it's not working for me

Answer 6

\[ \large n_4=2=(-1)\cdot(-2)=(-1)n_3=(-1)^3n_1 \]

Answer 7

look at the examples i gave u
u CAN figure this out
