EX 5D RECOGNITION OF GEOMETRIC SEQUENCES
IDENTIFYING GEOMETRIC SEQUENCES A sequence is an ordered set of numbers. A geometric sequence is one in which the first term is multiplied by a number, known as the COMMON RATIO, to create the second term which is multiplied by the common ratio to create the third term, and so on.
IMPORTANT! In a sequence that grows and where each term is positibe, the r value is GREATER than 1. In a sequence that decays and where each term is positive, the r value is between 0 and 1. In a sequence like 2, 2, 2, 2, 2….the r value is equal to 1. In a sequence like 2, -6, 18, -54…the r value is less than -1 In a sequence like -54, 18, -6, 2…the r value is between -1 and 0.
