WebAlgebra. Identify the Sequence -8 , -40 , -200 , -1000. −8 - 8 , −40 - 40 , −200 - 200 , −1000 - 1000. 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 5 5 gives the next term. In other words, an = a1rn−1 a n = a 1 r n - 1. Web= 3 + 5(n−1) = 3 + 5n − 5 = 5n − 2. So the 9th term is: x 9 = 5×9 − 2 = 43. Is that right? Check for yourself! Arithmetic Sequences are sometimes called Arithmetic Progressions (A.P.’s) Advanced Topic: Summing an Arithmetic Series.

Web5 years ago. Actually the explicit formula for an arithmetic sequence is a (n)=a+ (n-1)*D, and the recursive formula is a (n) = a (n-1) + D (instead of a (n)=a+D (n-1)). The difference is than an explicit formula gives the nth term of the sequence as a function of n alone, whereas a recursive formula gives the nth term of a sequence as a ... specificaties samsung s20 feWebJul 15, 2024 · The soil type of the field was brown loam.
