Question

Write the formula given the following arithmetic sequences. 9.6, 6.4, 3.2, 0, ...

Answer 1

The common difference I see here is -3.2 because we're adding -3.2 everytime

Answer 2

\( \color{Red}{\Rightarrow a_n = a_1 + (n - 1)d }\)

\( \color{Black}{\Rightarrow a_n = 9.6 + -3.2(n - 1) }\)

Answer 3

so the sequence would be tn = 3.2 – 9.6(n – 1)

Answer 4

Correct :) ^

Answer 5

No no...

Answer 6

Ahh thanks! :D

Answer 7

oh..

Answer 8

You switched em over lol

Answer 9
