WebMar 11, 2024 · How to find Common Difference if the sum of n terms of arithmetic progression is given? We can easily find the common difference if the sum of n terms of arithmetic progression is given by using the below steps: Step 1 : S n × 2 n = 2 a 1 + ( n – 1) d. Step 2 : S n × 2 n – 2 a 1 = ( n – 1) d. Step 3 : S n × 2 n – 2 a 1 ( n – 1) = d.

Web5 years ago. Actually the explicit formula for an arithmetic sequence is a (n)=a+ (n-1)*D, and the recursive formula is a (n) = a (n-1) + D (instead of a (n)=a+D (n-1)). The difference is than an explicit formula gives the nth term of the sequence as a function of n alone, whereas a recursive formula gives the nth term of a sequence as a ...
