Arithmetic Mean:

• If three terms are in A.P., then the middle term is known as the arithmetic mean (A.M.) between the other two i.e. if a,b,c are in A.P. then b=a+c/2 is the A.M. of a and c.
• If a₁, a₂, ...a_n are n numbers then the arithmetic mean (A) of these numbers is 
• The n numbers A₁, A₂......A_n are said to be A.M's between the numbers b and a if a, A₁, A₂,........A_n,b are in A.P. If d is the common difference of that A.P. then
  .

Problem: If the Ist and the 2nd terms of an A.P are 1 and -3 respectively, calculate the nth term and the addition of the Ist n terms.

Solution: Ist term = a, 2nd term = a + d where a = 1, a + d = -3,

                              Þ d = -4 (Common difference of A.P.)

                               we have a_n = a + (n -1)d

                              = 1 + (n - 1) (-4) = 5 - 4n
