ratio of 1,-5,25,-125
Answer (1)
Answer:To find the ratio of the sequence 1, -5, 25, -125, divide each term by the first term (1): - 1 ÷ 1 = 1- -5 ÷ 1 = -5- 25 ÷ 1 = 25- -125 ÷ 1 = -125 So, the ratio between consecutive terms is:-5 / 1 = -525 / -5 = -5 * -5 = -5 again? No, 25 / -5 = -5 does not match that. Wait, actually to find the common ratio: divide each term by its previous term: - (-5) / 1 = -5- 25 / (-5) = -5- (-125) / 25 = -5 The common ratio is -5. Thus, the ratio or common ratio of the sequence is -5.
