WebWe're given the first term = 15, therefore we need to find the value of the term that is 99 terms after 15. The arithmetic formula shows this by a+(n-1)d where a= the first term (15), n= # of terms in the series (100) and d = the common difference (-6). WebFind the 7 th term for the geometric sequence in which a 2 = 24 and a 5 = 3 . Substitute 24 for a 2 and 3 for a 5 in the formula a n = a 1 ⋅ r n − 1 .
