Question

the common difference of the a.p 1/c,1-c/c,1-2c/c

Answer 1

Given: The arithmetic progression 1/c, 1-c/c, 1-2c/c

To find: The common difference?

Solution:

• Now we have given the arithmetic progression:

                      1/c, 1-c/c, 1-2c/c

• Now common difference is difference of two consecutive terms.

• So common difference is:

                      C.D = 1-2c/c -  1-c/c

                      C.D = 1 - 2c - 1 + c / c

                      C.D = -c/c

                      C.D = -1

Answer:

               So the common difference is -1.
