Question

What is the common difference of an arithmetic sequence if its algebraic form is 2n+1/3

Answer 1

Answer:

D = Common Difference = 2/3

Explained Below

Step-by-step explanation:

• I Think It Should Be Like [2n+1]/3
• Put Integral Values Of n , Either Positive Or Negative
• If n = 1 , t1 = [2(1)+1]/3 = 3/3 = 1
• If n = 2 , t2 = [2(2)+1]/3 = 5/3
• If n = 3 , t3 = [2(3)+1]/3 = 7/3
• Common Difference D => t3-t2 or t2-t1
• Let's Take t3-t2 For A Simpler Calculation
• 7/3-5/3 = D = 2/3
