TASK 1. Classify each sequence as arithmetic sequence or not. If it is arithmetic sequence, find the common difference and the next term. 1. 1, 2, 3, 4, -5 2. 2, 5, 8, 11, ... 3. 1,0-1, -2, -3 4. 1, -3, 6, -9, ... 1. 3 5. 2' 2' ....

K Find the nth term and the indicated term of the arithmetic sequence whose initial term, a, and common difference, d, are given. a=5; d=10 an = ?; a16 = ? A. an=5+10n; a16 = 155 OB. an=-5+10n; a16 = 155 OC. an=-5-10n; a16 = 155 OD. an=-5+10n; a16 = 75

Which sequences are arithmetic and geometric?
