Algebra.Com's Answer #641827 by FrankM(1040)![]() ![]() You can put this solution on YOUR website! an = 2an-1 + 5 reads to me \"double the number and add 5\"\r \n" ); document.write( "\n" ); document.write( "If we start with 5, the next number is 2*5=10 10+5 = 15 \n" ); document.write( "then 15*2 = 30 30+5 =35\r \n" ); document.write( "\n" ); document.write( "Looks like choice B) 5, 15, 35, 75, ... \n" ); document.write( " |
