The first 10 multiples of 95: 95, 190, 285, 380, 475, 570, 665, 760, 855, 950

The multiples of 10 between 100 and 200 are 100, 110, 120, 130, 140, 150, 160, 170, 180, 190, and 200

There are 13 : 105, 112, 119, 126, 133, 140, 147, 154, 161, 168, 175, 182, 189.

Multiples of 19 include: 19, 38, 57, 76, 95, 114, 133, 152, 171, 190, 209, 228, 247, 266, 285, 304, 323, 342, 361, 380, etc... you must add 19 each time.19, 38, 57, 76, 95, 114, 133, 152, 171, 190, 209, 228, ...(The first 12 are given above, I'll leave the remaining infinite number of them for you to do.)38 57 76 95 114 133 152 171 190 and so on ...

203.3= 190 + (7%/100% * 190)= 190 + (7/100 * 190)= 190 + (0.07 * 190)= 190 + (13.3)= 203.3

The multiples of ten from 10 to 190 inclusive are 10, 20, 30, ..., 190. The average arithmetic mean of these numbers can be calculated by adding all the numbers together and then dividing by the total count of numbers. In this case, there are 19 numbers from 10 to 190, and the average arithmetic mean is 100.

Take the numbers in pairs. avg(10, 190) = 100 avg(20, 180) = 100 . . . avg(90, 110) = 100 It is easy to see the overall average is 100.
