Answer 2

Given :

• 1.7 , 2 , 2.3 , 2.6 , …(1)

To Find :

• Common Difference.

Solution :

• Consider the general expression of an arithmetic sequence.

$\longmapsto\tt{{a}_{1}{a}_{2}{a}_{3}.....{a}_{n}....(2)}$

Comparing equation (1) and (2) as follows.

$\longmapsto\tt{{a}_{1}=1.7}$

Common difference (d) of an arithmetic sequence can be obtained by choosing any term apart from first number in the sequence and subtiacting with a preceding term.

Consider 2 in the sequence and the prececding number therefore the Common difference can be calculated as follows.

$\longmapsto\tt{d={a}_{2}-{a}_{1}}$

$\longmapsto\tt{d=2-1.7}$

$\longmapsto\tt\bold{d=0.3}$

Hence, the first term if the sequence is 1.7 and the common difference of the sequence is 0.3.
