Find the first term of the arithetic sequence in which a24=509/4 and the common difference is 7/4

Step-by-step explanation:

Given,

and common difference,(d)

Let the first term of the arithetic sequence = a

To find, the first term of the arithetic sequence = ?

We know that,

The nth term of the arithmetic sequence,

⇒

⇒

⇒

⇒

⇒ a = 87

Hence, the first term of the arithetic sequence is 87.
