When three quantities are in A.P., then the middle one is said to be the arithmetic mean of the other two. That is, if a, b and c are in A.P., then b is the arithmetic mean of a and c. Since a, b and c are in A.P., the common difference ought to be constant, we have
b - a
or b + b
or 2b
or b
We should remember that between any two quantities we can insert any number of terms so that the resultant series is in A.P. Now we look at some examples wherein we will insert the required number of terms.
Example
Insert 15 arithmetic means between 4 and 68.
We are given the first term and the last term. The total number of terms including 4 and 68 are therefore 17. Since "a" is given we ought to find "d". The 17th term is given by T17 = a + 16d = 4 + 16d. Also the T17 term is given to be 68. Therefore,
d
Using the values of "a" and "d" we insert the required terms. The series will be 4, 8, 12, ..., 68.
If tanA+sinA=m and m2-n2 = 4vmn, show that tanA-sinA=n
Evaluate following limits. (a) (b) Solution There in fact isn't a whole lot to this limit. In this case because there is only a 6 in the denominator we'l
Example Factorize x 2 - 4x + 4. If we substitute x = 1, the value of the expression will be (1) 2 - 4(1) + 4 = 1 If we substitute x = -1, the value o
briefly explain how the famous equation for the loss of heat in a cylindrical pipe is derived
