Fill in the gaps in this arithmetic sequence: -3_,_,_,_,_,9
Answer (1)
Answer:The arithmetic sequence starts at -3 and ends at 9. To find the common difference, we can subtract the first term from the last term and divide by the number of gaps plus one: (9 - (-3)) / (6 - 1) = 12 / 5 = 2.4 Therefore, the common difference is 2.4. The completed sequence is: -3, -0.6, 1.8, 4.2, 6.6, 9
