A Sequence is a set of things (usually numbers) that are in order. Geometric Sequences. In a Geometric Sequence each term is found by multiplying the previous term by a constant. Example: 1, 2, 4, 8, 16, 32, 64, 128, 256, ... This sequence has a factor of 2 between each number.
Free sequence calculator - step-by-step solutions to help identify the sequence and find the nth term of arithmetic and geometric sequence types.
A Sequence is a list of things (usually numbers) that are in order. Infinite or Finite. When the sequence goes on forever it is called an infinite sequence, otherwise it is a finite sequence. Examples: {1, 2, 3, 4, ...} is a very simple sequence (and it is an infinite sequence) {20, 25, 30, 35, ...} is also an infinite sequence.
Finding Missing Numbers. To find a missing number, first find a Rule behind the Sequence. Sometimes we can just look at the numbers and see a pattern: Example: 1, 4, 9, 16, ? Answer: they are Squares (1 2 =1, 2 2 =4, 3 2 =9, 4 2 =16, ...) Rule: xn = n2. Sequence: 1, 4, 9, 16, 25, 36, 49, ... Did you see how we wrote that rule using "x" and "n" ?
1 1 , 2 2 , 4 4 , 8 8. This is a geometric sequence since there is a common ratio between each term. In this case, multiplying the previous term in the sequence by 2 2 gives the next term. In other words, an = a1rn−1 a n = a 1 r n - 1. Geometric Sequence: r = 2 r = 2.
