2520 is the smallest multiple of of first ten natural numbers.
The sum of the first 50 natural numbers is 1,251.
1 Sum of first n natural numbers = n(n+1)2[Formula.]2 Arthmetic mean of first n natural numbers = Sum of the numbers n[Formula.]3 = n(n+1)2n = n+124 So, the Arthmetic mean of first n natural numbers = n+12
The first six prime numbers:- 2, 3, 5, 7, 11 and 13
The sum of the first six prime numbers is 41 (2 + 3 + 5 + 7 + 11 + 13 = 41).

1 Sum of first n natural numbers = n(n+1)2[Formula.]2 Arthmetic mean of first n natural numbers = Sum of the numbers n[Formula.]3 = n(n+1)2n = n+124 So, the Arthmetic mean of first n natural numbers = n+12
The first six prime numbers:- 2, 3, 5, 7, 11 and 13
The first six triangular numbers are : 1,3,6,10,15,21. However, sometimes the first triangular number is regarded as 0 (zero) so you then have 0,1,3,6,10,15 as the first six triangular numbers.
Good question. 1+2+3+4+5=155=15 So the product of first five natural numbers is fifteen Natural numbers starts from one So we add first five natural numbers and get the right answer is fifteen
