find the common difference 1.5,8,11,14...2.7,10,13,16...3.-6,-2,2,6,10...4.5,10,20,40...5.3,9,27,81...6.
Answer (1)
Answer:Here are the common differences for each sequence: 1. 1.5, 8, 11, 14... - Common difference: 8 - 1.5 = 6.52. 7, 10, 13, 16... - Common difference: 10 - 7 = 33. -6, -2, 2, 6, 10... - Common difference: -2 - (-6) = 44. 5, 10, 20, 40... - This is not an arithmetic sequence (a sequence with a constant common difference). It's a geometric sequence where each term is multiplied by 2.5. 3, 9, 27, 81... - This is also a geometric sequence, where each term is multiplied by 3. Important Note: Arithmetic sequences have a constant difference between terms. Geometric sequences have a constant ratio between terms.
