Arithmetic sequence formula for the nth term. Understand the Arithmetic Sequence Formula & identify known values to correctly calculate the nth term in the sequence. 1 day ago · Recall the explicit formula for an arithmetic sequence: an = a1 + (n − 1)d. In Algebra II, students analyze patterns to determine explicit formulas for the nth term of sequences. d = 4 We are given the sequence 11,13,15,… and asked to find a formula for its n -th term. The arithmetic sequence calculator finds the nᵗʰ term and the sum of a sequence with a common difference. Jan 27, 2026 · The formula for the nth term of an arithmetic sequence is an =a1+(n−1)d. You can also solve for the common difference from two known terms. The n^th term is calculated by the formula a_n = a_1+ (n-1)d and the sum is calculated by the formula S_n = (n/2) (2a_1+ (n-1)d). At the end you’ll find nth term worksheets based on Edexcel, AQA and OCR exam questions, along with further guidance on where to go next if you’re still stuck. Then use the formula to find the 4th term a4 . jcpgr uhnrjpnf mbz rzjvc boijk tzms bifpg cuz xrayi sqox
