A theater has 49 seats in the first row, 53 seats in the second row, 57 seats in the third row, and so on. Answer the following questions:
\n" ); document.write( "-----
\n" ); document.write( "49,53,57, etc.
\n" ); document.write( "a(1) = 49
\n" ); document.write( "d = 53-49 = 4
\n" ); document.write( "---------------------------------
\n" ); document.write( "1) Can the number of seats in each row be modeled by an arithmetic or geometric sequence? (which type of sequence is it)
\n" ); document.write( "Answer: arithmetic
\n" ); document.write( "--------------------
\n" ); document.write( "2) Write the general term for a sequence an that gives the number of seats in row n.
\n" ); document.write( "a(n) = 49 + (n-1)4
\n" ); document.write( "-----------------------------------
\n" ); document.write( "3) How many seats are there in row 18?
\n" ); document.write( "a(18) = 49 + (17)*4 = 117
\n" ); document.write( "------
