If the common difference of ap is 3 a20-a15
WebThe common difference of an arithmetic sequence is the difference between two consecutive terms. It is denoted by 'd' and is found by using the formula, d = a (n) - a (n - 1). Here, a (n) = any term (n th term) a (n - 1) = the previous term of a (n) How to Find the Common Difference of Arithmetic Sequence?

WebCorrect option is A) Let the common difference of an A.P. be d. Then, a 18=a 1+17×d a 14=a 1+13×d Solving the two equations, a 18−a 14=a 1+17d−a 1−13d ⇒a 18−a 14=4d Substituting 4d=32, ⇒d=8 Was this answer helpful? 0 0 Similar questions If the common difference of an AP is 5, then what is a 18−a 13 ?
