Given:
Arithmetic progression is given as (a+3d),(a+d),(a-d)
To Find:
Find the next term T₄
Solution:
given progression is (a+3d),(a+d),(a-d),
As in the arithmetic progression, difference between the consecutive terms is constant which is known as common ratio.
T₁= (a+3d)
T₂=(a+d)
T₃=(a-d),
By the definition of AP
T₄-T₃=T₃-T₂
T₄=2T₃-T₂
=2(a-d)-(a+d)
=2a-2d-a-d
=a-3d
Hence the fourth term of the AP is (a-3d).

Given: AP series
Since we know that the common difference is
then the fourth term in the series will be
so the next term will be
