The sum of the first nine odd numbers is 81.
yes 9 25 49 81 121 All odd numbers squared are odd numbers
NO!!! '18' is EVEN because it ends in '8' '81' is ODD because it ends in '1'/ However, both numbers are multiples of '9'.

Oh, dude, you want me to add up all those odd numbers? Fine, fine, I'll humor you. So, the sum of the first 81 odd numbers is 81 squared, which is 6561. There you go, math whiz.
27 and 81 are the odd numbers. Since odd numbers are 1, 3, 5, 7 and 9, look at the last number and you will be able to tell if it's odd or even.
The answer is 685 odd numbers, 686 even numbers "between" 81 and 1453. If it said "to" you would include them.- 82 through 100 is 9 odd numbers and 10 evens- there are 50 (half) even/odd numbers per 100, so 100-1400 is 13 x 50 = 650 of each even/odd- there are 26 odd numbers, 26 even numbers in the remaining 52, since between doesn't include 1453.- total odd numbers is 9 + 650 + 26 = 685---The number range counting from 81 up to 1453 is 1453 - 81=1372, in which half the numbers are odd numbers or 1372/2 = 686. Since the question said "between" you would also have to exclude 1453, so the total result is 685.To test this, add twice 685 (1370) to 81 (one for each successive even then odd number) and you get 1451, the last odd number before 1453.*If you want the total of odd numbers from 1 to 1453 (including those numbers), it is 727: the number range includes 1453 numbers, 727 odd numbers and 726 even numbers. There are no half numbers.
NO!!! '18' is EVEN because it ends in '8' '81' is ODD because it ends in '1'/ However, both numbers are multiples of '9'.
3, 5, 7, 9, ... , 81.
25 (25+27+29=81)
no because 81 is an odd number. only even numbers are divisible by 2 evenly.
An odd number of odd numbers can not add up to an even number. There fore any 9 (odd) odd numbers can not add up to 50 (even).
