Question

Check my answer??
What is the d value of the following arithmetic sequence?
5, 2, -1, -4, -7,…

I got -3

Answer 1

Well generally when we have a arithmetic sequence we use the following "formula" not really a formula that's why I put it in quotations :P \[\huge t_2 - t_1 = t_3 - t_2 = d~~~~ \text{t = term}\]

Answer 2

\[2-5=-1-2 \implies - 3\] so you're good :)

Answer 3

Thank you!!!
