What is the common difference, the general term equation, and the 12th term of the arithmetic sequence? n a -10 -11 -12 -13 Hint: on = a + d(n - 1), where a is the first term and d is the common difference. O d= -3, on = 3-4n, 012 = -45 O d= -5, an =4-5n, 012 = -56 O d = 4, on = 5n - 4, 012 - 56 O d =-4, on =5-4n, 013 = -43How many terms are in the arithmetic sequence 6, 2, -2, ...,-102? Hint: an = a + d(n - 1) where a is the first term and d is the common difference O 27 O 28 O 29 O 30 Consider the arithmetic sequence presented in the table below. What is the first term,
