Given series: 28 ,3.5 ,? ,1.75, 112, 0.875
Observations:
- The series seems to be alternating between multiplying by 0.125 and dividing by 2.
- The first term (28) can be written as 3.5 * 8, and the next term (3.5) can be written as 28 * 0.125.
- Similarly, the third term can be obtained by multiplying the second term (3.5) by 0.125, and so on.
Using this observation, we can find the missing term as follows:
- The second term (3.5) multiplied by 0.125 gives 0.4375.
- The third term (missing) can be obtained by dividing the second term (3.5) by 2, which gives 1.75.
- Similarly, the fourth term (1.75) divided by 2 gives 0.875, which is the last term.
Therefore, the missing term in the series is 1.75.
