There is no "first" odd number because you can start as low as negative infinity and work your way up. If you meant first positive odd numbers, You can do the addition yourself.
The first 10 positive odd numbers are 1, 3, 5, 7, 11, 13, 17, 19, 23, and 29.
The first 20 odd numbers are: 13579111315171921232527293133353739.
The first 85 odd numbers are: 1 3579111315171921232527293133353739414345474951535557596163656769717375777981838587899193959799101103105107109111113115117119121123125127129131133135137139141143145147149151153155157159161163165167169.
1 + 3 + 5 + 7 + 9 + 11 = 36
64
the answer is 49.

No. As both negative and positive numbers can be odd, there is no first odd number, and therefore no 100th odd number. The 100th odd positive number is 199.
The sum of the first 100 odd numbers (1 through 199) is 10000 (ten thou)
There is no "first" odd number because you can start as low as negative infinity and work your way up. If you meant first positive odd numbers, You can do the addition yourself.
Positive odd integers less than 8 are: 1 3 5 and 7
The first 10 positive odd numbers are 1, 3, 5, 7, 11, 13, 17, 19, 23, and 29.
The sum of the first 1,000,000 positive even numbers is: 2 + 4 + 6 + 8 + ... + 2,000,000 The sum of the first 1,000,000 positive odd integers is: 1 + 3 + 5 + 7 + ... + 1,999,999 The difference between the two is: (2-1) + (4-3) + (6-5) + (8-7) + ... + (2,000,000-1,999,999). This is the same as: 1 + 1 + 1 + 1 + ... + 1. Well how many 1's are there? 1,000,000. So the difference is 1,000,000. Note that if the question asked for the difference between the sum of the first 1,000 positive even numbers and the sum of the first 1,000 positive odd numbers, the answer would be 1,000. The first n even numbers and odd numbers? n.
They are odd numbers.
1, 3, 5, 7, 9, 11
1+3+5+7+9=25
