Algebra.Com's Answer #7739 by venugopalramana(3286)![]() ![]() You can put this solution on YOUR website! the general expression for odd integer is 2n+1...since ..n is any integer, 2n is always even . if we add one to an even number we get an odd number \n" ); document.write( " so let the first odd integer be 2n+1 \n" ); document.write( " the second point to be noted is that consecutive odd integers differ by 2 . \n" ); document.write( " ( like 1,3,5 etc..)..so now \n" ); document.write( " 1st. number = 2n+1 \n" ); document.write( " 2nd.no.=2n+3 \n" ); document.write( " 3rd.no. = 2n+5 \n" ); document.write( " 4th.no. = 2n+7 \n" ); document.write( " 5th. no. =2n+9 \n" ); document.write( "sum of 1st and 5th. nos .=2n+1+2n+9=4n+10.......(1)\r \n" ); document.write( "\n" ); document.write( " three times the 4th. no. = 3*(2n+7)=6n+21 \n" ); document.write( " one less than above = 6n+21-1 = 6n+20.....(2) \n" ); document.write( " (1) = (2) ....so 4n+10=6n+20 \n" ); document.write( " 4n-6n=20-10=10 \n" ); document.write( "-2n=10 \n" ); document.write( "n=-5...so the five nos.are \n" ); document.write( " 1st. number = 2n+1 = 2(*-5)+1 = -9 \n" ); document.write( " 2nd.no.=2n+3................=-7 \n" ); document.write( " 3rd.no. = 2n+5................=-5 \n" ); document.write( " 4th.no. = 2n+7................=-3 \n" ); document.write( " 5th. no. =2n+9................=-1\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
