$n=\dfrac{a_n-a_1}{d}+1$

Step-by-step explanation:

Given : The formula to find a certain number in an arithmetic sequence is

a_n=a_1+d(n-1) , where a_n is the nth term , a_1 is the first term and d is the common difference.

To solve the formula for n , first subtract a_1 from both sides , we get

a_n-a_1=d(n-1)

Now, divide d on both sides , we get

$\dfrac{a_n-a_1}{d}=n-1$

Now, add 1 to the both sides , we get

$\dfrac{a_n-a_1}{d}+1=n$

$n=\dfrac{a_n-a_1}{d}+1$
