What is the next number? What is the 10th number? 0, 4, 8, 12, 16, ___ Arithmetic Sequence Finding for the next number The 10th number of the sequence 0, 4, 8, 12, 16, ____ is 36. Solution: Given the following: a₁ = 0 a₂ = 4 a₃ = 8 a₄ = 12 a₅ = 16 2. Find the difference between the second term and the first term. d = a₂ – a₁ d = 4 – 0 d = 4 3. Using d = 4, find the 10th term. a_n = a₁ + (n - 1) d a₁₀ = 0 + (10 – 1)4 a₁₀ = 0 + (9)4 a₁₀ = 0 + 36 a₁₀ = 36 4. Therefore, the 10th term of the sequence is 36 . Definition: An arithmetic sequence is a sequence of numbers such that the difference of any two consecutive terms of the sequence is a constant. While an arithmetic series is the sum of the terms of the arithmetic sequence.

Allan has 360 stamps. He gave some to Aaron and gave 1/4 of the remainder to Riza. If Allan has 225 stamps left, how many did he give Aaron? Answer: Allan gave 60 stamps to Aaron. Step-by-step explanation: Represent: Allans stamps: 360 Stamps Allan gave to Aaron : x Remainder or remaining stamps after Allan gave some to Aaron: 360-x Stamps given to Riza ⇒ 1/4 of the remainder: 1/4(360-x) Number of stamps left with Allan: 225 Equation: Allans stamps - (stamps given to Aaron + stamps given to Riza) = stamps left with Allan 360 - x + (1/4)(360-x) = 225 Find the x, the number of stamps Allan gave to Aaron: 360 - x + 90 - x/4 = 225 360 - x - 90 + x/4 = 225 360 - 90 - 225 = x - (x/4) 45 = x - (x/4) (4) 45 = x - (x/4) (4) 180 = 4x - x 180 = 3x 3x/3 = 180/3 x = 60 Allan gave 60 stamps to Aaron. Substitute, x=60: Rizas stamps = (1/4) (360 - 60) = (1/4) (300) = 75 stamps Check: 360 - (60 + 75) = 225 360 - 135 = 225 225 = 225 (True)
Morena and Pepe spent their vacation working as a service crew in one of the fast food restaurants. If their earning were in the ration 7:8 respectively, how much had Morena earned when Pepe has earned 6400$ Answer: Morena had earned $5,600. Step-by-step explanation: Ratio of Morenas earnings to Pepes earnings ⇒ 7:8 Pepes earnings ⇒ $6,400 Morenas earnings ⇒ x Proportion equation: 7 : 8 = x : 6,400 Find how Morena had earned, x: 8x = (7)(6,400) 8x/8 = 44,800/8 x = 5,600 Morena earned $5,600.
