A. Identify each sequence as arithmetic, geometric, or neither. If the sequence is arithmetic, write the common difference and the next two terms. If the sequence is geometric, write the common ratio and the next two terms. 1 H 1. -7, -3, 1, 5,... 3 1 3 4 5 1 HIN 4 5 6 . . 16 +B. Find what is asked. 1. geometric mean between 2 and 18 2. geometric mean between HIN andC. For each given geometric progression, find the formula for the nth term and the value of the indicated term. Also, find the indicated sum. 1. -3, 9, -27, 81, ...; ag; So 9 27 2. 2, 3, 2 4.'; 10 510D. Using the compound interest formula presented in example 4, find the final amount for each given principal amount, interest rate, and time. Note that compounded annually is k = 1, compounded semi-annually is k = 2, and compounded quarterly is k = 4. 1. P = 5 000; 5% compounded annually in 5 years 2. P = 12 000; 2% compounded quarterly in 4 yearsF. Read and solve each word problem. 1. Find the common ratio of a geometric progression whose ist term is 8 and 4th term is 27. 2. A colony of bacteria has an initial count of 12. If the bacteria count doubles every half hour, how many bacteria will there be after 10 hours
