Find the common ratio of the sequence.
2, –10, 50, –250, . . .
To find the common ratio of the sequence, we divide each term by the previous term.
-10 ÷ 2 = -5
50 ÷ -10 = -5
-250 ÷ 50 = -5
Therefore, the common ratio of the sequence is -5.
2, –10, 50, –250, . . .
-10 ÷ 2 = -5
50 ÷ -10 = -5
-250 ÷ 50 = -5
Therefore, the common ratio of the sequence is -5.
