Formula for nth term of an arithmetic sequence : an = a1 + (n - 1)d. Substitute a1 = 5, d = 5 and n = 25. a25 = 5 + (25 - 1) (5) = 5 + 24 (5) = 5 + 120. = 125. Example 4 : Find the 16th term of the
Solve NowExplanation: The th term of an arithmetic sequence with initial term and common difference is defined by the equation. Since the tenth and twelfth terms are two terms apart, the common
The nth term of an arithmetic sequence is given by : an=a1+(nā1)d an = a1 + (nā1)d To find the nth term, first calculate the common difference, d. Next multiply each term number of the
