This problem can be viewed as either a linear function or as an arithmetic sequence. The table of values give us a few clues towards a formula. The problem allows us to begin the sequence at whatever \(n\)−value we wish.
In exploring the realm of arithmetic sequences, I’ve delved into numerous problems and their corresponding solutions. The patterns in these sequences—where the difference between consecutive terms remains constant—allow for straightforward and satisfying problem-solving experiences.
The value of the nth term of an arithmetic sequence is given by the formula. an = a1 + (n - 1)d where a1 is the first term in the sequence, n is the position of the term in the sequence, and d is the common difference. Identify a1, n, and d for the sequence. ( n 1) d to find it.
Problem 1 Find [tex]a_{11}[/tex] if [tex]a_1=1[/tex], [tex]a_2=1[/tex] and [tex]a_{n}+a_{n-1}=2^{n}[/tex] Solution: The characteristic equation of the homogeneous recurrence relation is [tex]r+1=0[/tex], or [tex]r_1=-1[/tex].
