Q13) What comes in place of '?' 8, 12, 9, 13, 10, 14, 11, ?, ? 1) 15, 18 2) 15, 12 3) 13, 9 4) 9, 13 Solution: Pattern used is +4, -3. Required Numbers are = 11 + 4 = 15, 15 - 3 = 12 Hence, option 2. Q14) What comes in place of '?' 36, 32, 30, 26, 24, 20, 18, ?, ? 1) 14, 12 2) 16, 14 3) 16, 12 4) 14, 16 Solution: Pattern used is -4, -2. Required Numbers are = 18 - 4 = 14, 14 - 2 = 12 Hence, option 1. Q15) What comes in place of '?' 3, 5, 35, 10, 12, 1012, 17, ?, ? 1) 19, 1989 2) 22, 1012 3) 22, 1989 4) 19, 1719 Solution: This is an alternating addition series, with every third number composed of previous two numbers. Pattern used is +2, +5 and so on. Required Numbers are = 17 + 2 = 19, 1719 (Composed of 17, 19). Hence, option 4. Q16) What comes in place of '?' 13, 29, 15, 26, 17, 23, 19, ?, ? 1) 17, 17 2) 20, 19 3) 21, 20 4) 18, 15 Solution: The series above is made up of two alternating series 13, 15, 17, 19... and 29, 26, 23... Hence, option 3. |
