No odd perfect numbers are known; hence, all known perfect numbers are triangular. For example, the third triangular number is (3 × 2 =) 6, the seventh is (7 × 4 =) 28, the 31st is (31 × 16 =) 496, and the 127th is (127 × 64 =) 8128. In base 10, the digital root of a nonzero triangular number is always 1, 3, 6, or 9. Hence, every triangular ...
Question 2: What is the sum of the first 100 even numbers? Solution: We know that, from 1 to 100, there are 50 even numbers. Thus, n = 50. By the formula of sum of even numbers we know; S n = n(n+1) S n = 50(50+1) = 50 x 51 = 2550. Question 3: Find the sum of even numbers from 1 to 200? Solution: We know that, from 1 to 200, there are 100 even ...
If we start with an even number and each number in the sequence is 2 more than the previous number then we will get consecutive even integers. For example: 16,18, 20, … If we start with an odd number and each number in the sequence is 2 more than the previous number then we will get consecutive odd integers. For example: 33, 35, 37, …

There is a 40% chance that it will be an odd number. Explanation: The first five prime numbers are 2, 3, 5, 7, and 11. If one of the two numbers chosen is 2, the sum of the two numbers will be odd. 2 + 3 = 5 2 + 5 = 7 2 + 7 = 9 2 + 11= 13 But, if both numbers chosen are odd, the sum will be an even number. 3 + 5 = 8 3 + 7 = 10 3 + 11 = 14 5 + 7 = 12 5 + 11 = 16 7 + 11 = 18 So, there are four ...
There are 2 main types of odd numbers which are consecutive odd numbers and composite odd numbers. Consecutive Odd Numbers. If ‘a’ is an odd number, then ‘a’ and ‘a + 2’ are called consecutive odd numbers. A few examples of consecutive odd numbers can be. 15 and 17; 29 and 31; 3 and 5; 19 and 21 etc.
The expected outputs are: The sum of odd numbers from 1 to 1000 is: 250000 The sum of even numbers from 1 to 1000 is: 250500 The absolute difference between the two sums is: 500

History. Nicomachus, at the end of Chapter 20 of his Introduction to Arithmetic, pointed out that if one writes a list of the odd numbers, the first is the cube of 1, the sum of the next two is the cube of 2, the sum of the next three is the cube of 3, and so on.

A number like “4” is 1 away from being threeven (remainder 1), while the number 5 is two away (remainder 2). Being “threeven” is just another property of a number. Perhaps not as immediately useful as even/odd, but it’s there: we can make rules like “threeven x threeven = threeven” and so on. But it’s getting crazy.

the next number so we had x, x + 1, and x + 2 for our ﬁrst, second, and third number respectivly. With even or odd numbers they are spaced apart by two. So if we want three consecutive even numbers, if the ﬁrst is x, the next number would be x + 2, then ﬁnally add two more to get the third, x + 4. The same is 2
