The same sequence may be defined in three ways: 1) f(x) = 3x + 4 for x = {1, 2, 3, }, 2) a1 = 4 and an + 1 = an + 3 for n = {1, 2, 3, } and 3) an = 4 + 3(n − 1) for n = {1, 2, 3, }. they are all supposed to generate the same values, but one version may contain an error. if one version contains an error, identify the one with the error and fix it. a) none of these have errors, they all generate the same sequence. b) f(x) = 3x + 4 for x = {1, 2, 3, } it should say f(x) = 3x + 1 for x = {1, 2, 3, }. c) an = 4 + 3(n − 1) for n = {1, 2, 3, } it should say an = 3 + 4(n − 1) for n = {1, 2, 3, }. d) a1 = 4 and an + 1 = an + 3 for n = {1, 2, 3, } it should say a1 = 3 and an + 1 = an + 4 for n = {1, 2, 3, }.
