Practice CBSE Class 9 Sequences in the app →A list of numbers arranged in a particular order is called a:The 5th term (t₅) of the sequence of odd numbers 1, 3, 5, 7, ... is:The 6th triangular number is:If the explicit rule for a sequence is uₙ = 3n + 2, find u₁₀:Which of the following is a sequence with COMMON DIFFERENCE 4?For the sequence 7, 12, 17, 22, …, what is the 20th term?What is the explicit rule (formula) for the nth term of the sequence 4, 7, 10, 13, …?What is the SUM of the first 10 natural numbers (1 + 2 + 3 + … + 10)?In the sequence 1, 4, 7, 10, 13, …, what is the SUM of the first 5 terms?In a sequence, t₅ = 17 and t₁₀ = 37. If it is arithmetic, what is the common difference?Find the sum: 1 + 3 + 5 + 7 + … + 99 (first 50 odd numbers):A sequence is an ordered list of:Each number in a sequence is called a:In the square numbers 1, 4, 9, 16, the second term is:The sequence 6, 12, 24, 48, 96 is:Consecutive odd numbers differ by:A sequence with a constant difference between terms is an:A sequence where each term is multiplied by a fixed number is a:The fixed step in an arithmetic progression is called the:The fixed multiplier in a geometric progression is the:The nth term of an AP is:The nth term of a GP is:In the AP 1, 4, 7, 10, the common difference is:In the sequence 11, 7, 3, the common difference is:A formula that gives a term from its position n is:The sum of the first n natural numbers is:The fifth triangular number, 15, equals:Each square number is the sum of:A rule that uses the previous two terms builds which sequence?Is 1, -1, 1, -1 a geometric progression?The sequence 240, 280, 320 is an AP with common difference:
