Direct link to Alex T.'s post It seems to me that 'expl, Posted 6 years ago. a 3 After knowing the values of both the first term ( [latex]{a_1}[/latex] ) and the common difference ( [latex]d[/latex] ), we can finally write the general formula of the sequence. How do you find the sum of the arithmetic sequence having the data given #a_1=5#, d = 7, n = 120? For this, lets use Equation #1. Enrolling in a course lets you earn progress by passing quizzes and exams. We have different formulas associated with an arithmetic sequence used to calculate the n th term, the sum of n terms of an AP, or the common difference of a given arithmetic sequence.
