Math Problem Statement
Write an explicit formula for ath term of the sequence 32, 28, 24 ....
Solution
The given sequence is: This sequence is an arithmetic sequence because the difference between consecutive terms is constant. The common difference is: The first term is 32.
The explicit formula for the -th term of an arithmetic sequence is given by: Substituting the values of and , we get: Simplifying:
Thus, the explicit formula for the -th term of the sequence is:
