The first three odd numbers are 1, 3, and 5. Their sum is 1 + 3 + 5 = 9.
The first 20 odd numbers are: 13579111315171921232527293133353739.
The first 10 positive odd numbers are 1, 3, 5, 7, 11, 13, 17, 19, 23, and 29.
The first 85 odd numbers are: 1 3579111315171921232527293133353739414345474951535557596163656769717375777981838587899193959799101103105107109111113115117119121123125127129131133135137139141143145147149151153155157159161163165167169.
The sum of the first 8,000 odd numbers 64,000,000.
1,3,5 and 7The first four odd numbers are 1, 3, 5 and 7. Odd numbers are not divisible by two.
The first three odd numbers are 1, 3, and 5. Their sum is 1 + 3 + 5 = 9.
9801 * The sum of the first two odd numbers (1+3) is 4, or 22 * The sum of the first three odd numbers (1+3+5) is 9, or 32 * The sum of the first four odd numbers (1+3+5+7) is 16, or 42 * ...and so on So the sum of the first 99 odd numbers, using the pattern above, would be 992 or 9801.
You cannot. The sum of 5 odd numbers must be odd. 30 is not odd.You cannot. The sum of 5 odd numbers must be odd. 30 is not odd.You cannot. The sum of 5 odd numbers must be odd. 30 is not odd.You cannot. The sum of 5 odd numbers must be odd. 30 is not odd.
the sum of the first three numbers is 1 + 3+5= 9
You cannot. The sum of 5 odd numbers is always odd. 30 is not odd.
35
You cannot. The sum of 5 odd numbers must be odd.

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.
1, 3, 5, and 7
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.
