WebApr 10, 2024 · We have to find the 25th and 40th term so n = 25 and n = 40. 25th term. The nth term of an arithmetic sequence given by the formula. a n = a 1 + (n - 1) d. Substituting the values we get. a 25 = 3 + (25 - 1) 5. a 25 = 3 + (24) 5. a 25 = 3 + 120. a 25 = 123. 40th term. The nth term of an arithmetic sequence given by the formula. a n = a 1 + (n ... WebTo find the next few terms in an arithmetic sequence, you first need to find the common difference, the constant amount of change between numbers in an arithmetic sequence. Once you know the common difference, you can use it to find those next terms! This tutorial takes you through that process, so be sure to check it out!
