Explanation Formula used: n th term of a Arithmetic sequence: The n th term of a Arithmetic sequence is given by a n = a 1 + ( n − 1 ) d , where a 1 is the first term of the sequence, n is the number of the term and d is the common ratio between consecutive term. Calculation: The starting salary is $54,000 and the increment per year is $3,600. Thus, the double salary will be, 54 , 000 × 2 = 108 , 000 Here, the first term is a 0 = 54 , 000 and the common difference is d = 3 , 600 . Thus, the n th term of a Arithmetic sequence will be, a n = 54 , 000 + ( n − 1 ) × 3 , 600 = 54 , 000 + 3 , 600 n − 3 , 600 = 50 , 400 + 3 , 600 n Obtain the number of years for which the salary is $108,000 as follows
