Answer: 25
Explanation To find the next number in the series 11, 14, 18, 21 , let's analyze the pattern of differences: 14 − 11 = 3 14 - 11 = 3 18 − 14 = 4 18 - 14 = 4 21 − 18 = 3 21 - 18 = 3 The differences alternate between +3 and +4 . Following this pattern: After 21 21 , add 4 : 21 + 4 = 25
Answer: 12
Explanation If 2 x 8 = 5, 3 x 27= 11, 6x24=7 then 5 x 40=12 8/2 = 4+ 1 = 5 27/3= 9+ 2 = 11 24/6= 4+ 3 = 7 40/5= 8+ 4 = 12
