Question 1:
20, 32, 45, 59, 74 A. 95
B. 90
Feedback The differences between the consecutive terms of the series are 12
13, 14, 15, 16,
2nd term = 1st term + 12 = 20 + 12 = 32
3rd term = 2nd term + 13 = 32 + 13 = 45
4th term = 3rd term + 14 = 45 + 14 = 59
5th term = 4th term + 15 = 59 + 15 = 74
Thus, ? = 6th term = 5th term + 16 = 74 + 16 = 90
13, 14, 15, 16,
2nd term = 1st term + 12 = 20 + 12 = 32
3rd term = 2nd term + 13 = 32 + 13 = 45
4th term = 3rd term + 14 = 45 + 14 = 59
5th term = 4th term + 15 = 59 + 15 = 74
Thus, ? = 6th term = 5th term + 16 = 74 + 16 = 90
C. 85
