For problems 1 - 4, write the first five terms of the sequence. (write your final answer as a sequence!) a =1 do =4 a, = 2 a =2, a, = 3 1) 2) a = 20m- 3) a = (an ) + 1 4) For problems 5 - 12, determine if the sequence is arithmetic, geometric, or neither. Then, write a recursive rule for the sequence...even if it's "neither"!! 5) -7, 0, 7, 14, 21. ... 6) 4, -12, 36, -108, 324, ... 7) 16, 9, 7, 2, 5, ... arithmetic/geometriceither arithmetic/geometriceither arithmetic/geometriceither 8) 5, 513, 15, 15 3, 45, ... 9) -3, -2, 5,-3, -2. ... 10) 54, 43, 32, 21, 10, ... arithmetic/geometriceither arithmetic/geometriceither arithmetic/geometriceither 11) 8, 4, 2. 2, 1, ... 12) 44, 11 1 11 11 4'16 64 arithmetic/geometriceither arithmetic/geometriceither
