    Re: Number series [1]....

    Answer is 79...

    Solution

    The next number is formed by adding the previous number with the individual digit in the number...

    eg:-
    25=17+1+7
    32=25+2+5
    37=32+3+2 and so on

    Final value is 71+1+7=79

    hi

    i got 97 since
    result

    25-17=8


    32-25 =7 result is decreased by 1 compared to previous result

    37-32=5 result is decreased by 2 compared to prev result



    47-37=10 result is doubled compared to prev result


    58-47=11 result is increased by1 compared to previous result


    71-58 =13 result is increased by 2 compared to previous result


    now the previous result should b doubled!

    i.e 13*2=26


    therefore 71+26=97


    thats what i thought!

    bye

    hi manoj


    yes , iwill take care of it!
    but I dont write solution only when i answer the puzzle first(or say before 3hrs or so)!the only reason y i dont give solution is that i want others to think!( i want others to read and they should equally enjoy the question) .

    What i think(personal view) is that giving solutions in the very first post itself kills the anxiety of others!
    I hop u r getting my point!There is no reason other than this!
    bye
