Determine if the fоllоwing sequences аre geоmetic. If they аre, find the common rаtio, the term named in the problem, and the explicit formula. If not, simply type "not geometric" in each blank. -3, 9, -27, 81, ...   Is the sequence geometric? [yesorno3]  If yes, state the common ratio: [r] If yes, find = [term8] If yes, state the explicit formula: = [explicitgeo]     -1, -2, -6, -24, ... Is the sequence geometric? [yesorno4]  If yes, state the common ratio: [rnope] If yes, find = [term7] If yes, state the explicit formula: = [explicitnongeo]
