Example 6 Is 1, 2, 4, 8, 16, โ€ฆ a geometric progression? If so, what is the common ratio? Given sequence 1, 2, 4, 8, 16, โ€ฆ If its GP, then common ratio is same So, we need to show (๐Ÿ^๐’๐’… ๐’•๐’†๐’“๐’Ž)/(๐Ÿ^๐’”๐’• ๐’•๐’†๐’“๐’Ž)=" " (๐Ÿ‘^๐’“๐’… ๐’•๐’†๐’“๐’Ž)/(๐Ÿ^๐’๐’… ๐’•๐’†๐’“๐’Ž) Now, ๐Ÿ’/๐Ÿ=๐Ÿ/๐Ÿ 2 = 2 Since common ratio is same, it is a GP And, Common ratio = r = 2
