Then use the formula: (-b±√(b²-4ac)÷(2a) 2 of 6 Geometric Sequence Type of sequence where the successive terms bear a constant ratio known as a common ratio e.g 2,4,6,8... having a common ratio of 2. 3 of 6 Arithmetic Sequence A sequence where each term is obtained by adding a fixed number to its previous term e.g 1,5,9,13... with the "common difference" being 4. 4 of 6 Quadratic Sequence A sequence where the first differences are NOT same but the second differences are the same e.g 1, 2, 4, 7... with a common second difference of +1 5 of 6 Fibonacci Sequence A sequence where every term is the sum of the last two preceding terms e.g 0, 1, 1, 2, 3, 4, 7, 11... 6 of 6
