Answer:
To identify the pattern in the series 11, 7, 7, 539, we can observe that each number is obtained by multiplying the previous number by a specific factor. The pattern is as follows:
11 * 1 = 11
11 * 0.5 = 5.5 (rounded to 7)
7 * 1 = 7
7 * 77 = 539
So, following this pattern:
539 * 0.5 = 269.5 (rounded to 270)
Therefore, the next number in the series is 270.
