Find an explicit formula for the arithmetic sequence -5,13,31,49

an explicit formula for the arithmetic sequence -5,13,31,49 is   .

Step-by-step explanation:

Here we have an arithmetic sequence -5,13,31,49 . We need to find an explicit formula for the arithmetic sequence  .Let's find out:

Let   be terms of an A.P , common difference is :

⇒

⇒

⇒

⇒

We know that general term of an Arithmetic Progression ( A.P) is :

⇒

So , Here we will have  

⇒

⇒

⇒

Therefore , an explicit formula for the arithmetic sequence -5,13,31,49 is   .
