Q. What kind of sequence is this?11,33,99,297,…Choices:(A) arithmetic(B) geometric(C) both(D) neither
Check Arithmetic Sequence: Let's first check if the sequence is an arithmetic sequence by finding the differences between consecutive terms.11,33,99,297,…The differences are:33−11=2299−33=66297−99=198
Verify Differences: Now, let's check if these differences are the same (which is required for an arithmetic sequence).22, 66, 198, ...The differences between these are:66−22=44198−66=132These differences are not the same; therefore, the sequence is not arithmetic.
Check Geometric Sequence: Next, let's check if the sequence is a geometric sequence by finding the ratios between consecutive terms.11,33,99,297,…The ratios are:1133=33399=399297=3
Verify Ratios: Now, let's check if these ratios are the same (which is required for a geometric sequence).3,3,3,…The ratios between consecutive terms are the same; therefore, the sequence is geometric.
