What is the sum of first 10 multiples of 6?
First 10 multiples of 6 are 6, 12, 18, 24, 30, 36, 42, 48, 54, 60. This forms an AP with first term a = 6 and common difference, d = 6. Thus, sum of first 10 multiples of 6 is 330.
How are the digits of multiples of nine sum?
The Sum of Digits for Multiples of Numbers It is well known that the digits of multiples of nine sum to nine; i.e., 9→9, 18→1+8=9, 27→2+7=9,…, 99→9+9=18→1+8=9, 108→1+0+8=9, etc. Less well known is that the sum of digits of multiples of other numbers have simple patterns although not so simple as the case of nine.
