That's impossible. Adding up an odd number of odd numbers will give an answer that is an odd number. 50 is an even number. So adding up 5(5 is an odd number) odd numbers will not give 50, an even number.
2 + 4 + 6 + 8 + 10 + 12 + 14 + 16 + 18 + 20 = 110 There you go.
As the number is odd it must end in an odd digit; the odd digits are 1, 3, 5, 7, 9 and the smallest is 1 which is the sum of 1 and 0. Thus the smallest 7-digit number which meets your criteria is 1,001,001
The sum of the first 100 odd numbers (1 through 199) is 10000 (ten thou)
You can work this out by realizing that the sum of the first x odd numbers is equal to x2.Consider the following examples:The first three odd numbers: 1 + 3 + 5 = 9The first five odd numbers: 1 + 3 + 5 + 7 + 9 = 25The first ten odd numbers: 1 + 3 + 5 + 7 + 9 + 11 + 13 + 15 + 17 + 19 = 100In each case, the number of odds you're adding together is the square root of their sum. This means that the first 1500 consecutive odd numbers have a sum of 15002, which equals 2250000, or two and a quarter million.
1+3+5+7+9+11+13+15+17+19 equals 100.

Basic maths !... 1+3+5+7+9+11+13+15+17+19=100
The first ten positive numbers total 55.
It is 110.
The first ten odd numbers
The sum of the first 10 natural numbers is 51.
To find the sum of the first ten prime numbers, you first have to find what the first 10 prime numbers are. They are 2, 3, 5, 7, 11, 13, 17, 19, 23, and 29. Added together they equal 129.
