Explanation Given: The first term a = − 3 and the common ratio r = − 2 . Approach: A geometric sequence is a sequence of the form: a , a r , a r 2 ,… The number a is the first term, and r is the common ratio of the sequence. The n t h term of the a geometric sequence is given as, a n = a r n − 1 …… ( 1 ) Calculation: Substitute − 3 for a and − 2 for r in equation ( 1 ) . a n = − 3 ( − 2 ) n − 1 …… ( 2 ) Let a 4 is the fourth term to calculate a 4 , substitute 4 for n in equation ( 2 )
