\n" ); document.write( "The sequence of the last two digits of increasing powers of 7 will form a repeating pattern. Use the length of that pattern to find the answer.

\n" ); document.write( "07
\n" ); document.write( "49
\n" ); document.write( "43
\n" ); document.write( "01
\n" ); document.write( "07
\n" ); document.write( "....

\n" ); document.write( "That is a very short pattern with length 4.

\n" ); document.write( "The exponent 8910, divided by 4, leaves remainder 2, so the answer is the 2nd number in the repeating pattern: 49

\n" ); document.write( "ANSWER: 49
