1. Write the first term of the arithmetic sequence whose first term is 7, and whose common difference is 9. 2.Find the 17th term of the arithmetic sequence whose first term is -6 and whose common difference is -2.
3.If the second term of an arithmetic progression is -17 and the fifth term is -11, find the fifteenth term

first term: 7

find the 17th term : 102

fifteent term: 10

Step-by-step explanation:

hababa

the answer is 489

step-by-step explanation:

the terms of a geometric sequence can be found by beginning with the first term and multiplying by the common ratio repeatedly. a recursive formula for a geometric sequence with common ratio r is given by an=ran−1 a n = r a n − 1 for n≥2 n ≥ 2 .
