What is the 15th term of the sequence 4, 8, 6, 32 is this sequence arithmetic geometric or neither 24, 30, 36, 42

2. the anwser is simple just add 6 and get your awnser 48

1. 18 is your awnser

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!

The first one is 2/3the second is 1/160the third is 4/125
