what is the lower limit of 25-29

If it is not a continuous variable, 25. If continuous, 24.5.

25/2-29/2

To find the lower limit of a range, subtract the range from the higher limit. In this case, the higher limit is 29 and the range is 25-29.

So, to find the lower limit, subtract the range from the higher limit:
29 - (25-29)

Simplifying the expression, we have:
29 - 4 = 25

Therefore, the lower limit of the range 25-29 is 25.
