It can be finite or infinite.<\/p>\n<p>Types of Sequences:<br \/>\n  Arithmetic Sequence: Each term increases or decreases by a constant difference, \\(d\\). Formula: \\(a_n = a_1 + (n-1)d\\).<br \/>\n  Geometric Sequence: Each term is multiplied by a constant ratio, \\(r\\). Formula: \\(a_n = a_1 \\cdot r^{n-1}\\).<br \/>\n  Harmonic Sequence: Reciprocals of an arithmetic sequence, e.g., \\(1, \\frac{1}{2}, \\frac{1}{3}, \\dots\\).<\/p>\n<p>A series is the sum of the terms of a sequence, written as \\(s = a_1 + a_2 + a_3 + \\dots\\).<\/p>\n<p>Types of Series:<br \/>\n  Arithmetic Series: Sum of an arithmetic sequence. Sum formula: \\(s_n = \\frac{n}{2} (a_1 + a_n)\\) or \\(s_n = \\frac{n}{2} [2a_1 + (n-1)d]\\).<br \/>\n  Geometric Series: Sum of a geometric sequence. Sum of first \\(n\\) terms: \\(s_n = a_1 \\frac{1-r^n}{1-r}\\) (for \\(r \\neq 1\\)). Infinite sum: \\(s = \\frac{a_1}{1-r}\\) if \\(|r| < 1\\).\n  Other Series: Harmonic series (\\(1 + \\frac{1}{2} + \\frac{1}{3} + \\dots\\)) diverges; telescoping series cancel terms.\n\nKey Concepts:\nConvergence: A series converges if its sum approaches a finite limit (e.g., infinite geometric series with \\(|r| < 1\\)).\nDivergence: A series diverges if the sum is infinite or undefined.\nTests for Series: Use ratio test, root test, or integral test to determine convergence.\n\n\n\n\n<h3>Table of contents<\/h3>\n<ul class=\"article_list\">\n<li><a href=\"#1\">Part 1: OnlineExamMaker AI quiz maker &#8211; Make a free quiz in minutes<\/a><\/li>\n<li><a href=\"#2\">Part 2: 20 sequences and series quiz questions &#038; answers<\/a><\/li>\n<li><a href=\"#3\">Part 3: AI Question Generator &#8211; Automatically create questions for your next assessment <\/a><\/li>\n<\/ul>\n<p><img decoding=\"async\" src=\"https:\/\/onlineexammaker.com\/kb\/wp-content\/uploads\/2025\/08\/1532-sequences-and-series.webp\" alt=\"\"\/><\/p>\n<h3 id=\"1\">Part 1: OnlineExamMaker AI quiz maker &#8211; Make a free quiz in minutes<\/h3>\n<p>Still spend a lot of time in editing questions for your next sequences and series assessment?

What is the next term in the arithmetic sequence: 3, 7, 11, 15, &#8230;?<br \/>\n   A) 18<br \/>\n   B) 19<br \/>\n   C) 20<br \/>\n   D) 21<br \/>\n   <strong>Answer<\/strong>: B) 19<br \/>\n   <strong>Explanation<\/strong>: The common difference is 4 (7 &#8211; 3 = 4), so add 4 to 15 to get 19.<\/p>\n<p>2. Find the sum of the first 5 terms of the arithmetic sequence: 2, 5, 8, 11, 14.<br \/>\n   A) 30<br \/>\n   B) 35<br \/>\n   C) 40<br \/>\n   D) 45<br \/>\n   <strong>Answer<\/strong>: C) 40<br \/>\n   <strong>Explanation<\/strong>: Use the formula for the sum of an arithmetic series: S_n = n\/2 * (a_1 + a_n). Here, n=5, a_1=2, a_5=14, so S_5 = 5\/2 * (2 + 14) = 5\/2 * 16 = 40.<\/p>\n<p>3.

What is the 5th term of the geometric sequence with first term 2 and common ratio 3?<br \/>\n    A) 48<br \/>\n    B) 54<br \/>\n    C) 162<br \/>\n    D) 81<br \/>\n    <strong>Answer<\/strong>: B) 54<br \/>\n    <strong>Explanation<\/strong>: a_n = a * r^(n-1). Here, a_5 = 2 * 3^(5-1) = 2 * 3^4 = 2 * 81 = 162, wait correction: 2*3^4=2*81=162, so D) 81 is wrong; it&#8217;s C) 162.<\/p>\n<p>15.
