8/23/2023 0 Comments Number sequence formulaLet us try to rewrite 3 × n + -2 by making the first term appear in the expression.ģ × n + -2 = 3 × n + -3 + 1 (since -2 = -3 + 1) We will now look for the arithmetic sequence formula using the algebraic expressions.ģ × n + -2 is the algebraic expression for 1, 4, 7, 10, 13, 16, 19. The way that we modeled the arithmetic sequences above with algebraic expressions is a shortcut. When n = 3, which represents the second term, we get -8 × 3 + 78 = -24 + 78 = 54Īgain, the algebraic expression works! Arithmetic sequence formula.When n = 2, which represents the second term, we get -8 × 2 + 78 = -16 + 78 = 62.When n = 1, which represents the first term, we get -8 × 1 + 78 = -8 + 78 = 70.We can therefore model the sequence with this algebraic expression: -8 × n + 78. The number that comes right before 70 in the sequence is 78. The number we subtract to each term is -8. Let n represent any term number in the sequence. When n = 3, which represents the third term, we get 3 × 3 + -2 = 9 + -2 = 7Ģ) Let us try to model 70, 62, 54, 46, 38.When n = 2, which represents the second term, we get 3 × 2 + -2 = 6 + -2 = 4.When n = 1, which represents the first term, we get 3 × 1 + -2 = 3 + -2 = 1. We can therefore model the sequence with this algebra expression: 3 × n + -2.Ĭheck to see if the algebra expression works: The number that comes right before 1 in the sequence is -2. The number of possible KeyForge three-house combinations is also a tetrahedral number, Te n−2 where n is the number of houses.Here is a trick or " recipe per se" to quickly get an algebraic expression! 1) Let us try to model 1, 4, 7, 10, 13, 16, 19. The cumulative total number of gifts after each verse is also Te n for verse n. Te 12 = 364 is the total number of gifts "my true love sent to me" during the course of all 12 verses of the carol, " The Twelve Days of Christmas". Popular culture Number of gifts of each type and number received each day and their relationship to figurate numbers
