Arithmetic Geometric Sequence: 3, 5, 7, 9, Recursive: f(n) f(n-1) + 2 Explicit: f(n) 2n + 1 n f(n) -2 -3 -1 -1 0 1 1 3 2 5 7 Table: Graph: Sequence: 1, 2, 4, 8, Recursive: f(n) f(n-1) 2 Explicit: f(n) 1 2 n-1 2 n f(n) -2 1/8 -1 0 1 1 2 2 3 4 Table: Graph: This is only an example. The recursive definition for the geometric sequence with initial term a and common ratio r is an an r a0 a. However, the ratio between successive terms is constant. If you are redistributing all or part of this book in a print format, This is not arithmetic because the difference between terms is not constant. Want to cite, share, or modify this book? This book uses the The twelfth term of the sequence is 0, a 12 = 0. Practicing arithmetic sequences worksheets help us to predict and evaluate the outcome of a situation. The comments deal with the puzzle origins and design or analysis techniques. of the puzzle the sequential terms are in a constant ratio, the sequence. All the puzzles are provided with hints, detailed solutions, and brief comments. Benefits of Arithmetic sequences Worksheets Sequences play an important role in our life. Arithmetic and geometric sequences worksheet algebra 1 (with answer key) A. Ī n = a 1 + ( n − 1 ) d a n = a 1 + ( n − 1 ) dġ0 = a 1 + ( 7 − 1 ) ( −2 ) 10 = a 1 + ( 7 − 1 ) ( −2 )ġ0 = a 1 + ( 6 ) ( −2 ) 10 = a 1 + ( 6 ) ( −2 )įind the twelfth term, a 12, a 12, using theįormula with a 1 = 22, n = 12, and d = −2. Arithmetic sequences worksheets help students build basic ideas on sequences and series in mathematics. To first find the first term, a 1, a 1, use theįormula with a 7 = 10, n = 7, and d = −2.
