This is ageometric sequencesince there is a commonratiobetween eachterm. In this case, multiplying the previoustermin thesequenceby−12-12gives the nextterm. In other words,an=a1rn−1an=a1rn-1. Geometric Sequence:r=−12r=-12
A geometric sequence is generated by multiplying the common ratio with the given term to get the next term. We will find the nth term of the geometric sequence with the help of the following formula: Tn=arn−1 a is the first term and r is the common ratio...
To find the first six terms of the sequence defined by the given conditions, we will follow these steps: 1. Identify the first term: The first term a1 is given as 1. a1=1 2. Define the recursive formula: The (n+1)th term is obtained by adding n to the nth term. This can be ...
Set up a system of four equations with four variables to find the coefficients a, b, c and d. Use the values given in the sequence as if they were points on a graph in the form (n, nth term in sequence). It is easiest to start with the first 4 terms, as they are usually smal...
