some definitions suppose that a1 , a2 , an is a sequence of real numbers
{"Image DocumentName": "Some DefinitionsSuppose that a1,a2, \u2026 an is a sequence of real numbers.", "Image ImageDescription": "A subsequence of this sequence is a sequence of the form ai1, ai2, \u2026, aim, where 1 \uf0a3 i1 < i2 < < im \uf0a3 n. A sequence is called strictly increasing if each term is larger than the term that precedes it. A sequence is called strictly decreasing if each term is smaller than the one that precedes it. Example: {1, 5, 6, 2, 3, 9} is a sequence. {5,6,9} is a subsequence that is strictly increasing.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
