Algebra.Com's Answer #699414 by htmentor(1343)![]() ![]() You can put this solution on YOUR website! First find the common ratio, r: \n" ); document.write( "r = (2p-2)/(p-1) = 2(p-1)/(p-1) = 2 \n" ); document.write( "Thus r = 2 = (3p-1)/(2p-2) -> 3p - 1 = 4p - 4 -> p = 3 \n" ); document.write( "So the 1st 3 terms are 2, 4, 8 \n" ); document.write( "Since r > 1, the series does not converge and the sum is infinite. \n" ); document.write( " |
