\n" ); document.write( "1) how many terms are in the finite geometric series and find its sum . 2(0.1)^5 +2(0.1)^6 + .......+2(0.1)^13
\n" ); document.write( "----------------------------------------------------------------\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "It is easy to calculate the number of terms:  from  5 to  13 inclusively,  i.e.  13-4 = 9.
\n" ); document.write( "=================================================================\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "2) the other one is  2+ 2(0.1) +2(0,1)^2 +.....+2(0.1)^25.
\n" ); document.write( "-----------------------------------------------------------------\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The number of terms is from  0  to  25 inclusively, i.e.  25 + 1 = 26.
\n" ); document.write( "=================================================================\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Regarding the sums,  please calculate them yourself using standard formulas for the sum of geometric progression. \r
\n" ); document.write( "\n" ); document.write( "See,  for example,  the lesson  Geometric progressions  in this site.\r
