The sum of the first 10 multiples of 3 is 165.
The first 10 multiples of which number?
There are no multiples of ten.
-the first 10 multiples of 20 are 20,40,60,80,100,120,140,160,180, and 200. :)
10. They are the first ten multiples of 9.
10+20+30 = 60
The sum of the first 10 positive integers 1,2,3,4,5,6,7,8,9 and 10 is 55. The sum of the first 10 negative integers -1,-2,-3,-4,-5,-6,-7,-8,-9 and -10 is -55. The sum of the first 10 positive plus the sum of the first 10 negative integers is 0
5 + 10+15+20=50 ans
The first 10 multiples of 10 are: 10, 20, 30, 40, 50, 60, 70, 80, 90, and 100.
The first 10 multiples of 10 are: 10, 20, 30, 40, 50, 60, 70, 80, 90, and 100.
There is an infinite number of multiples for 62. The first ten positive multiples of 62 are:62124186248310372434496558620
If half of the sum is 90 then the full sum must be 180. The three consecutive multiples of 10 which add up to 180 are 50, 60 and 70.
