Arithmetic Sequence: d = 5
\n" ); document.write( "\"a%5Bn%5D+=+a%5B1%5D+%2B+%28n-1%29d\"
\n" ); document.write( "\"a%5B100%5D+=+3+%2B+%2899%295\" = 498 Step I
\n" ); document.write( ".......\r

\n" ); document.write( "complete the Calculation to find sum = 25,050
\n" ); document.write( "\"S%5B100%5D=50%283+%2B+498%29\" = 25,050 Step 3
\n" ); document.write( "this is the way one would find the Sum regardless of the Number of terms.
