Love you

Please is it a must for us to calculate for the minus sign?

[@yungarins6962]

But the 5th term can’t be negative since the sequence was progressing

[@sampsonahomah3264]

Please, why can't we limit the answer to a positive figure by converting the positive 9 to index form (9 = 3^2) ? In this case, we could equate r to 3 since they would have the same indices or power. Thank you.

[@DavetutsAcademy]

It's because (-3)^2=9. So you have both as feasible solutions

[@skieee7948]
