To find any term value in the sequence we can just substitute its position for n and evaluate. For example, the 9th term in the sequence is 3,840. a n = 15 ( 2 ) n 1 a 9 = 15 ( 2 ) 9 1 a 9 = 15 ( 2 ) 8 the change in term position is 8 a 9 = 15 ( 256 ) we must multiply a 1 by 256 to get a 9 a 9 = 3840 Consider the sequence 40 , 120 , 360
