Q. What kind of sequence is this?56,66,76,86,…Choices:(A) arithmetic(B) geometric(C) both(D) neither
Check for Arithmetic Sequence: Determine if the sequence is arithmetic by checking if the differences between consecutive terms are constant.Calculation: 66−56=10, 76−66=10, 86−76=10.The differences between consecutive terms are all equal to 10.
Confirm Arithmetic Sequence: Since the differences between consecutive terms are constant, we can conclude that the sequence is an arithmetic sequence.
Check for Geometric Sequence: To check if the sequence is also geometric, we need to see if there is a common ratio between consecutive terms.Calculation: 5666, 6676, 7686. Let's calculate these ratios.5666≈1.1786, 6676≈1.1515, 7686≈1.1316.The ratios between consecutive terms are not equal.
Confirm Geometric Sequence: Since the ratios between consecutive terms are not equal, the sequence is not a geometric sequence.
Final Conclusion: Based on the calculations in the previous steps, we can conclude that the sequence is an arithmetic sequence but not a geometric sequence.
