For the following APs, write the first term and the common difference:
$-5, -1, 3, 7, ……$
Given:
Given A.P. is $-5, -1, 3, 7, …………$.
To do:
We have to write the first term and the common difference.
Solution:
In the given A.P.,
$a_1=-5, a_2=-1, a_3=3$
Therefore,
First term $a=a_1=-5$ Common difference $d=a_2-a_1=-1-(-5)=-1+5=4$.
The first term $a$ is $-5$ and the common difference $d$ is $4$.
