Answer 2

Answer:

$\huge{\boxed{\rm{\red{an=2n}}}}$

Step-by-step explanation:

Given :-

2,4,6,8,...

To find:-

Algebraic expression of the given series

Solution:-

Given series:2,4,6,8...

First term (a)=2

Common difference (d)=4-2=2

=6-4=2

=8-6=2

Since ,the common difference is same

2,4,6,8... are in the AP

Now we know that the general term

an=a+(n-1)d

=>an=2+(n-1)2

=>an=2+2n-2

=>an=2n

Answer:-

Algebraic expression of the given series=2n
