Multiples are not 5, 10, 15 20, 25. WRONG! It means like 1. Because, 1x25= 25. Therefore it is a multiple. 2x nothing= 25. 5x5= 25 MULTIPLE!

The sum of the first 25 numbers is 25*26/2 = 325 So the sum of the first 25 multiples of 12 is 325*12 = 3900
the multiples of 4 are 4,8,12,16,20,24,28,32,36,40,44,48,52,56,60 those are the multiples of 4
30, 60, 90, 120, 150
28,32,36,40,44

25 and 50
The first 4 multiples of three are:3x13x23x33x4
The sum of the first 25 numbers is 25*26/2 = 325 So the sum of the first 25 multiples of 12 is 325*12 = 3900
the multiples of 4 are 4,8,12,16,20,24,28,32,36,40,44,48,52,56,60 those are the multiples of 4
They are: 25, 50 and 75
The first 4 multiples of 4 are: 4, 8, 12, and 16.
30, 60, 90, 120, 150
The first 3 multiples of 4 are: 4, 8, and 12.The first 3 multiples of 9 are: 9, 18, and 27.
