Identify the missing term in the descending series: 82, 73, 64, 55, ...
Answer:
46
The pattern involves subtracting 9 from the preceding number to obtain the next one (82 - 9 = 73, 73 - 9 = 64). Applying this logic, 55 - 9 equals 46.
112
Find the next number in the sequence: 55, 48, 41, 34, ...
Answer:
27
By checking the difference between terms (55 - 48 = 7), we observe that the series decreases by a constant value of 7 at each step. Subtracting 7 from 34 gives 27.
113
What is the next term in the series: 100, 90, 80, 70, ...?
Answer:
60
This is a descending arithmetic progression where each term decreases by exactly 10. Subtracting 10 from the last term (70 - 10) provides the next number in the series, which is 60.
114
Find the missing number: 12, 27, 42, 57, ...
Answer:
72
The sequence follows a constant additive pattern. The difference between consecutive terms is 15 (27 - 12 = 15). Adding 15 to the last provided term (57 + 15) results in 72.
115
What will be the next number in the series: 1, 14, 27, 40, ...?
Answer:
53
This arithmetic series progresses by adding 13 to the previous number. Checking the differences: 14 - 1 = 13, and 27 - 14 = 13. Applying this rule to the last term, 40 + 13 equals 53.
116
Identify the next number in the sequence: 8, 19, 30, 41, ...
Answer:
52
Analyzing the gaps between the numbers (19 - 8 = 11, 30 - 19 = 11), we find a uniform addition of 11 at each step. To find the next number, we add 11 to 41, which yields 52.
117
Which number comes next in the series: 18, 27, 36, 45, ...?
Answer:
54
The series represents consecutive multiples of 9, starting from 18 (which is 9 x 2). The constant difference between the terms is 9. Adding 9 to the final term of 45 gives the correct next term, 54.
118
Find the next term in the sequence: 2, 9, 16, 23, ...
Answer:
30
This sequence increments by a fixed amount at each step. Calculating the difference (9 - 2 = 7, 16 - 9 = 7) reveals a common difference of 7. Continuing this pattern, 23 + 7 equals 30.
119
What is the next number in the series: 5, 13, 21, 29, ...?
Answer:
37
By observing the differences between consecutive terms (13 - 5 = 8, 21 - 13 = 8), we can establish that this is an arithmetic progression with a common difference of 8. Adding 8 to 29 gives 37.
120
Find the missing number in the series: 11, 22, 33, 44, ...
Answer:
55
The pattern in this series involves adding a constant value of 11 to the previous term to get the next term. Consequently, adding 11 to the last term (44 + 11) yields the next number, which is 55.
