That is incorrect.
1) The answer is 65,536 because in the sequence, each term was multiplied by 2 to get the next number. Following the pattern, the 15th term is 65,536. This is a geometric sequence.
2) The pattern is arithmetic because with each term, 6 was added to get the next term in the sequence.
The difference between geometric and arithmetic sequences is in geometric sequences, you multiply by a number by the terms to get the next term in the sequence, and in arithmetic sequence, you add a number to each term to get the next term in the sequence. Cheers!
