Take the number two (2) and then add to it two, then do that again two times, then again another tw0 tmes, and then again... repeat until you have reached 100 numbers in your ist. Don't forget the zero as your starting point! ;-)
The sum of the first 100 odd numbers is 10,000.
Adding up all the even numbers from the first (2) to the fiftieth (100): [(100 + 2) / 2] x 50 = 2550 Can you see the logic of this method?
The sum of the 25 primes less than 100 is even (it is 1060).The first prime number is 2. Every other prime number is odd.So, of the 25 primes less than 100, one is even and 24 are odd.Any two odd numbers sum to an even number. Therefore, an even number of odd numbers has an even sum. So the sum of 24 odd numbers is even.Therefore, the sum of the 25 primes less than 100 is even.
The first numbers of pi is 3.14159265358979323846264338327950288419716939937510 58209749445923078164062862089986280348253421170679
The only even prime number (not only from 1 to 100, but in general) is 2. All other even numbers are multiples of 2, and therefore, by definition, not prime numbers.
The first 100 even numbers are: 2 468101214161820222426283032343638404244464850525456586062646668707274767880828486889092949698100102104106108110112114116118120122124126128130132134136138140142144146148150152154156158160162164166168170172174176178180182184186188190192194196198200.
The first 100 whole, even numbers are: 2468101214161820222426283032343638404244464850525456586062646668707274767880828486889092949698100102104106108110112114116118120122124126128130132134136138140142144146148150152154156158160162164166168170172174176178180182184186188190192194196198200.
The sum of the first 100 positive even numbers is 10,100.
The sum of the first 100 even numbers is 10,100
The sum of all the first 100 even numbers is 10,100.
The sum of the first 100 positive even numbers is 10,100.
n*(n+1)=sum 100*(100+1)=10100
The average of the first n even numbers is n+1, so 101.The average of the first n even numbers is n+1, so 101.The average of the first n even numbers is n+1, so 101.The average of the first n even numbers is n+1, so 101.
The even numbers up to 100 are: 2 468101214161820222426283032343638404244464850525456586062646668707274767880828486889092949698100.
even numbers 1-100
Every number has 1 as a multiple. 1*100 = 100 1*7 = 7 As 1 is an odd number there are no numbers with only even multiples.
You do not need a conjecture; you can calculate the answer. The answer is 10,100
