An arithmetic sequence has a third therm of 9 and the 12th term is 12. a) Find the general term of the sequence. b) Find the 100th term of the sequence.
Added by Jessica M.
Step 1
An arithmetic sequence is defined by its first term (denoted as \( a \)) and the common difference (denoted as \( d \)). The \( n \)-th term of an arithmetic sequence can be expressed as \( a_n = a + (n - 1)d \). Show more…
