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.
2442
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.
2443
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.
2444
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.
2445
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.
2446
Identify the next term in the series: 7, 14, 21, 28, ...
Answer:
35
This is an arithmetic series where each term increases by a constant difference of 7. It can also be viewed as the multiplication table of 7. To find the next term, simply add 7 to the last number: 28 + 7 = 35.
2447
What will come next in the given series: 3, 6, 9, 12, ...?
Answer:
15
The given series is a simple arithmetic sequence based on the multiples of 3. The difference between any two consecutive numbers is 3 (e.g., 6 - 3 = 3, 9 - 6 = 3). Therefore, adding 3 to the last term (12 + 3) results in 15.
2448
Find the next number in the series: 2, 4, 6, 8, ...
Answer:
10
This number series follows a clear arithmetic progression where each subsequent number increases by a fixed value. By finding the difference between consecutive terms (4 - 2 = 2), we determine the common difference is 2. Adding 2 to the final term, 8 + 2, gives the next number in the sequence, which is 10.

Pipe A fills a tank 4 times as fast as Pipe B. Together they fill the tank in 24 minutes. How long will Pipe A alone take to fill the tank?
Answer:
30 minutes
Step 1: Assume B's rate is 1x. Since A is 4 times faster, A's rate is 4x. The combined rate is 5x. Step 2: The total capacity = combined rate * time = 5x * 24 = 120x. Step 3: Time for A alone = Total capacity / A's rate = 120x / 4x = 30 minutes.

Pipe A fills a tank 3 times as fast as Pipe B. If together they fill it in 36 minutes, how long will Pipe B alone take to fill the tank?
Answer:
144 minutes
Step 1: Let B's rate be 1x, so A's rate is 3x. Their combined rate is 4x. Step 2: Total work capacity = combined rate * time = 4x * 36 = 144x. Step 3: Time taken by B alone = Total capacity / B's rate = 144x / 1x = 144 minutes.
