Algebra.Com's Answer #687693 by rothauserc(4718)![]() ![]() You can put this solution on YOUR website! The solution is \n" ); document.write( ": \n" ); document.write( "a(n) = n^3 where a(n) is the nth term \n" ); document.write( ": \n" ); document.write( "we determine this by using the difference approach \n" ); document.write( ": \n" ); document.write( "0, 1, 8, 27, 64 \n" ); document.write( ": \n" ); document.write( "level one differences between terms is \n" ); document.write( ": \n" ); document.write( "1, 7, 19, 37 \n" ); document.write( ": \n" ); document.write( "level 2 differences between level 1 differences is \n" ); document.write( ": \n" ); document.write( "6, 12, 18 \n" ); document.write( ": \n" ); document.write( "level 3 differences between level 2 differences is \n" ); document.write( ": \n" ); document.write( "6, 6 \n" ); document.write( ": \n" ); document.write( "the level 3 differences are the same so we know we have a n^3 term \n" ); document.write( ": \n" ); document.write( "n^3 term gives us 0, 1, 8, 27, 64 so we are done \n" ); document.write( ": \n" ); document.write( "Note that in some cases it may be necessary to add or subtract a constant as well as multiply the exponent term by a constant \n" ); document.write( ": \n" ); document.write( " \n" ); document.write( " |
