Algebra.Com's Answer #18268 by venugopalramana(3286) You can put this solution on YOUR website! SUM OF A G.P.TO INFINITE TERMS,WHERE COMMON RATIO IS LESS THAN 1 IS GIVEN BY \n" ); document.write( "S=A/(1-R)...WHERE A IS FIRST TERM AND R = C.R. \n" ); document.write( "HERE A=16 AND R = -4/16=-1/4 \n" ); document.write( "S=16/(1+1/4)=16/(5/4)=16*4/5=64/5 \n" ); document.write( " |
