Explanation Given information: The geometric sequence is a n = 2 ( 5 ) n − 1 . Calculation: If the terms a , a r , a r 2 , a r 3 , … are in geometric sequence then the n t h term a n of a geometric sequence can be calculated as. a n = a r n − 1 …… (1) Here, a is the first term of geometric sequence, n is the number of terms and r is the common ratio. The common ratio r is the ratio of two consecutive terms of the sequence. The given geometric sequence is, a n = 2 ( 5 ) n − 1 …… (2) Substitute 1 for n in the equation (1) to obtain the first term of the geometric sequence as, a 1 = 2 ( 5 ) 1 − 1 = 2 ( 5 ) 0 = 2 Therefore, the first term of the geometric sequence is 2
