Step-by-Step Solution

To solve this problem, let's analyze the sequence of numbers given: 2,4,8,16,32,64 2, 4, 8, 16, 32, 64 .

First, let's calculate the ratio between each pair of consecutive terms in the sequence:

  • The ratio of the second term 4 4 to the first term 2 2 is 42=2\frac{4}{2} = 2.
  • The ratio of the third term 8 8 to the second term 4 4 is 84=2\frac{8}{4} = 2.
  • The ratio of the fourth term 16 16 to the third term 8 8 is 168=2\frac{16}{8} = 2.
  • The ratio of the fifth term 32 32 to the fourth term 16 16 is 3216=2\frac{32}{16} = 2.
  • The ratio of the sixth term 64 64 to the fifth term 32 32 is 6432=2\frac{64}{32} = 2.

Each consecutive term is obtained by multiplying the previous term by 2 2 . Therefore, this sequence is a geometric sequence where each term is ×2\times 2 times the preceding term.

This consistent multiplication factor shows that the sequence's property is that of a geometric progression with a common ratio r=2 r = 2 .

In conclusion, the identified property of the sequence is that each term is multiplied by 2 2 , which is option ×2 \times 2 .

Answer

×2 \times2
