QuestionFind the general formula for the sequence {−1/2,0,1/2,1,…}\{-1/2, 0, 1/2, 1, \ldots\}. Options: an=(−1/2)n+1a_n=(-1/2)n+1, an=n+1/2a_n=n+1/2, an=(1/2)n−1a_n=(1/2)n-1, an=n−1/2a_n=n-1/2.

Studdy Solution
Combine like terms.
an=n/2−1a_n = n/2 -1So, the general formula for the sequence {−1/2,0,1/2,1,…}\{-1 /2,0,1 /2,1, \ldots\} is an=n/2−1a_n = n/2 -1.
