Question

What is the 11th term of the sequence 1,2,4,8,16

Answer 1

The answer is 1024 or B

Answer 2

Begin by adding each number by the same number. The sum is then added by its number. Continue to do this method until you reach the eleventh term. Remember to include the first term. 

1 + 1 = 2 - first term
2 + 2 = 4 - second term
4 + 4 = 8 - third term
8 + 8 = 16 - fourth term...
16 + 16 = 32
32 + 32 = 64
64 + 64 = 128
128 + 128 = 256
256 + 256 = 512
512 + 512 = 1024
1024 + 1024 = 2048 - eleventh term
