They are members of the infinite set of numbers of the form 360*k where k is an integer.
The multiples of 7 between 200 and 400 are: 203, 210, 217, 224, 231, 238, 245, 252, 259, 266, 273, 280, 287, 294, 301, 308, 315, 322, 329, 336, 343, 350, 357, 364, 371, 378, 385, 392, 399. The sum of all the multiples of 7 between 200 and 400 is 8,729.
The only stable pattern is that the difference between the sum of all the digits in odd locations and the sum of all digits in even locations is a multiple of 11.For example, 5678*11 = 62458Sum of odd locations = 6 + 4 + 8 = 18Sum of even locations = 2 + 5 = 7Difference = 18 - 7 = 11 which is a multiple of 11.
1 x 11 = 112 x 11 = 223 x 11 = 33. ------. 66
Any multiple of 35, like 280.

300 Find the difference (500-100=400) then halve the sum(200). Add the halved sum to the lowest number in the equaion(100) or subtract the halved sum(200)from the largest number in the equation(500) one:500-100=400 two:400/2=200 Three: 200+100=300 or 500-200=300

There are 8 numbers between 100 and 200 (inclusive) that have a digit sum of 12, namely: 129, 138, 147, 156, 165, 174, 183, 192.
There are nine of them. They are:108117126135144153162171180

sum just means add and 100 and 100 when added together is 200.
this isn't a place to do your math homework.
The sum of the whole numbers that are divisible by three and which lie between 100 and 200 is 4950.

Finding the sum is adding two numbers together. The product comes from multiplying them together. Therefore, the sum of 100 and 100 is 200. The product of 100 and 100 is 10,000. Thus, the difference (which comes from subtracting two numbers) between the two is 9,800.
