If 15th and 11th term of an A.P are 3 and 23 respectively. Is 40 the term of the sequence ?
\n" ); document.write( "Equations:
\n" ); document.write( "a + 14d = 3
\n" ); document.write( "a + 10d = 23
\n" ); document.write( "--------------------
\n" ); document.write( "4d = -20
\n" ); document.write( "d = -5
\n" ); document.write( "-----
\n" ); document.write( "Then a = 3 -14(-5) = 73
\n" ); document.write( "-----
\n" ); document.write( "Is 40 the term of the sequence ?
\n" ); document.write( "Comment:: That is a strange question.
\n" ); document.write( "General term of the sequence is a(n) = 73 + (n-1)(-5)
\n" ); document.write( "---
\n" ); document.write( "Solve, if possible::
\n" ); document.write( "73 + (n-1)(-5) = 40
\n" ); document.write( "5(n-1) = 33
\n" ); document.write( "n-1 = 33/5
\n" ); document.write( "n = 38/5
\n" ); document.write( "----
\n" ); document.write( "No; 40 is not a term of the sequence.
\n" ); document.write( "----
