    The odd integers from 1 to 2001 are 1, 3, 5, …1999, 2001.
    This sequence forms an A.P.
    Here, first term, a = 1 Common difference, d = 2
    Here, a+(n−1)d = 2001
    => 1+(n−1)(2) = 2001
    => 2n−2 = 2000
    => n = 1001
    Sn = n/2[2a+(n−1)d]
    ∴ Sn = 1001/2[2×1+(1001−1)×2]
    =1001/2[2+1000×2]
    =1001/2×2002 =
    1001×1001 =1002001
    Hence, the sum of odd numbers from 1 to 2001 is 1002001.

    hlo nishant! tumhe drne ki bilkul bhi jarurat nhi h...12th koi monster nhi h....It's too gud that you are concerned...and I will advise You that you should prepare for your boards evenly from the very beginning (bahut kam log krte hein) so that you have nothing to worry about at the end..... first of all you should understand the chapters and clear the basics...with the help of your teachers,tutor .... then you should move to the next step solving questions as much as you can but remember whatever extra things you want to do at the time of your boards (sample paper, last year papers,HOTS questions,1 markers) ,you should assemble all that in advance from all the sources you like slowly slowly....so that you should not have to waste your precious days close to your boards googling that.. I think ye pta sab ko hota h lekin follow kam hi karte hein.... hmare sath bhi esa hi hua h experience se bta rhi hu.... So be serious from the starting and you will definitely achieve your goal.... THANKS..
