Write a variable expression to describe the rule for each sequence. Then find the hundredth term.
\n" ); document.write( "1. 3, 6, 9, 12, ...
\n" ); document.write( "---
\n" ); document.write( "An arithmetic sequence with a = 1 and d = 3
\n" ); document.write( "---
\n" ); document.write( "a(n) = 1 + (n-1)3 where n is the number of the term.
\n" ); document.write( "---
\n" ); document.write( "a(100) = 1 + 99*3
\n" ); document.write( "a(100) = 1 + 297
\n" ); document.write( "a(100) = 298
