The first 100 odd natural numbers are the number 1-201, ignoring all even numbers.
If you think about this for a moment, you realize that :
1+201 = 202
3+199 = 202
5+197 = 202
etc.
With this, you can pair up all of your numbers leaving you with 50 pairs, all equaling 202.
Ergo: 50*202 = 10100 is your sum.
This is very easy. Simply square the number: 100 squared (100 x 100) = 10,000. So, the sum of the first 100 odd numbers is 10,000.
The first 20 odd numbers are: 13579111315171921232527293133353739.
Their sum is 10000.
The sum of 5 odd numbers must be odd and 100 is even. So there cannot be such a set.
The first 85 odd numbers are: 1 3579111315171921232527293133353739414345474951535557596163656769717375777981838587899193959799101103105107109111113115117119121123125127129131133135137139141143145147149151153155157159161163165167169.
The first 100 odd whole numbers are: 13579111315171921232527293133353739414345474951535557596163656769717375777981838587899193959799101103105107109111113115117119121123125127129131133135137139141143145147149151153155157159161163165167169171173175177179181183185187189191193195197199.
The sum of the first 100 odd numbers is 10,000.
The sum of the first 10 odd whole numbers is 100.
The sum of the first 100 odd numbers (1 through 199) is 10000 (ten thou)
100
100
This is very easy. Simply square the number: 100 squared (100 x 100) = 10,000. So, the sum of the first 100 odd numbers is 10,000.
The last digit in the product of the first 20 odd natural numbers can be determined by looking at the pattern of the units digit in the multiplication of consecutive odd numbers. The units digit of the product of consecutive odd numbers alternates between 1 and 5. Since there are 10 odd numbers between 1 and 19, and 20 is also an odd number, the last digit in the product of the first 20 odd natural numbers is 5.
It is 100^2=10000
Oh honey, the sum of the first 100 odd numbers is 10,000. You see, the formula for the sum of the first n odd numbers is n^2, and since 100 is the 50th odd number, 50^2 equals 10,000. So, there you have it, darling.
The sum is 10,000.
To determine the number of odd numbers between 100 and 200, we need to consider that odd numbers are integers that are not divisible by 2. The first odd number in this range is 101, and the last odd number is 199. To find the total count, we can subtract the first odd number from the last odd number and divide by 2, then add 1 to include both endpoints. So, (199 - 101) / 2 + 1 = 50 odd numbers.
