For the following arithmetic progressions write the first term a and the common difference d:$0.3, 0.55, 0.80, 1.05, …………$

Given:

Given A.P. is $0.3, 0.55, 0.80, 1.05, …………$.

To do:

We have to write the first term a and the common difference d.

Solution:

In the given A.P.,

$a_1=0.3, a_2=0.55, a_3=0.80$

Therefore,

First term $a=a_1=0.3$
Common difference $d=a_2-a_1=0.55-0.3=0.55-0.30=0.25$.

The first term $a$ is $0.3$ and the common difference $d$ is $0.25$.
