By using the formula for an arithmetic series. This is basically obtained by reasoning: The sum of the first 25 numbers is the same as 25 multiplied by the average of those numbers; the average in this case is simply (1 + 25) / 2.

you didn't give numbers to go with the question so I can't say, but there are too many numbers to count in between those decimals, you can keep adding more numbers after the decimal for eternity and still not reach the maximum number. 0.2 0.3, 0.4 are the first numbers of ones that are inbetween and 0.5 is the only other one other than those that there are.
What does the squiggly line mean when it starts at zero on a graph?
it means that from zero to the first number next to the graph is not in the same order as the other numbers. for example it might me 0,10,15,20,25. there will be a squiggly line after 0 because 0+5 is not 10 and the pattern here is adding 5 each time. hope this helps:)
