Identify the Sequence 1 , 2 , 4 , 8 , 16. 1 1 , 2 2 , 4 4 , 8 8 , 16 16. 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.
Find the Next Term. Free sequence calculator - step-by-step solutions to help identify the sequence and find the nth term of arithmetic and geometric sequence types.
Feb 18, 2016 · Explanation: The difference between successive terms is not a constant, so the sequence is not an arithmetic sequence. Checking to see if the sequence might be geometric, we see the successive terms are all a multiple of 2 times the previous term. a1 = 1 = 20. a2 = a1 ×2 = 21. a3 = a2 ×2 = a1 ×22 = 22. a4 = a3 ×2 = a1 ×23 = 23.

Jan 18, 2024 · The formulas to calculate a sequence's nth term (arithmetic and geometric sequences); Interesting integer sequences (prime numbers, Fibonacci numbers, figurate numbers); And much more. We will teach you how to use our versatile tool and give you some examples of sequence calculations.
If we start indexing at $n = 1$, we get $$a_n = 2^{\lceil \log_2 n\rceil}$$where $\lceil - \rceil$ is the ceiling function.
