Sample text

Each number on the inside of this triangle comes from adding the two numbers above it. If you happen to know about algebra, yet another way to make this triangle is to foil out (x + y)N.

For example, XXX equals 30. If a smaller symbol appears left of a larger symbol, it subtracts. For example, XL is 40 and XCV is 95 (but not VC, as X rather than V is used before C). Otherwise, smaller numbers appear to the right, in which case they add. For example, XXXIII equals 33. As a last example of writing Roman numerals, XLV is 45, as the X subtracts 10 from 50, while the V adds 5. Example 1. This sequence begins with Roman numeral X (ten) and counts upward by ones. X, XI, XII, XIII, XIV, XV, XVI, XVII, XVIII...

4, 6, 9, 11, 14, 16, 19... The next two numbers are 21 (since 19 + 2 = 21) and 24 (since 21 + 3 = 24). Example 3. This sequence is made by alternately multiplying by 2 and dividing by 3. Beginning with 324, multiplying by 2 makes 648, dividing by 3 makes 216, multiplying by 2 makes 432, dividing by 3 makes 144, and so on. 324, 648, 216, 432, 144... ∞ 34 ∞ 300+ Mathematical Pattern Puzzles The next two numbers are 288 (since 144 × 2 = 288) and 96 (since 288 / 3 = 96). ) #1 2, 7, 22, 67, 202, ______, ______, ______, ______ #2 3, 9, 8, 14, 13, 19, 18, ____, ____, ____, ____ #3 1022, 510, 254, 126, 62, ____, ____, ____, ____ #4 #5 #6 1, 3, 6, 18, 36, 108, 216, _______, _______, _______, _______ 101, 99, 95, 93, 89, ____, ____, ____, ____ 256, 128, 144, 72, 88, 44, 60, ____, ____, ____, ____ ∞ 35 ∞ #7 #8 #9 6 Multiple Operations 3, 5, 9, _____, 33, _____, _____, 257, _____ 5, 7, 15, 17, 35, 37, 75, 77, 155, _____, _____, _____, _____ 1, 3, 6, 10, 15, 21, ____, ____, ____, ____ #10 4, 6, 9, 13, 18, 24, ____, ____, ____, ____ #11 #12 100, 51, 98, 53, 95, 56, 91, 60, ____, ____, ____, ____ 8, 4, 12, 6, 24, 12, 60, 30, 180, 90, 630, ______, ______, ______, ______ ∞ 36 ∞ #13 #14 300+ Mathematical Pattern Puzzles 50, 52, 47, 55, 43, 59, 38, 64, 32, ____, ____, ____, ____ 10, 50, 20, 100, 70, 350, 320, 1600, ________, ________, ________, ________ #15 #16 1, 3, 6, 9, 18, 22, 44, 49, 98, ______, ______, ______, ______ 2, 2, 1, 2, 1, 3, 2, 8, 7, 35, 34, ______, ______, ______, ______ #17 a, d, c, f, e, h, g, j, i, l, k, ___, ___, ___, ___ #18 1, 2, 6, 9, 10, 14, 17, 18, 22, 25, 26, 30, 33, ______, ______, ______, ______ ∞ 37 ∞ 6 Multiple Operations #19 2, 5, 10, 9, 12, 24, 23, 26, 52, 51, 54, 108, 107, ______, ______, ______, ______ #20 8, 6, 24, 12, 10, 40, 20, 18, 72, 36, 34, 136, 68, ______, ______, ______, ______ ∞ 38 ∞ 7 Digits Each sequence in Chapter 7 involves changing one or more digits of a multidigit number.
