To finish the sequence, find the following numbers: 1.5,2,3, 4.5, 6.5, ?, ?, ?,

Answer: 9, 12, 15.5

To find the next numbers in the sequence, identify the pattern in the differences between consecutive terms. The differences are +0.5, +1, +1.5, +2, indicating that the difference itself increases by 0.5 each time. Following this pattern, the next differences should be +2.5, +3, and +3.5. Applying these to the last given number (6.5) yields 6.5 + 2.5 = 9, then 9 + 3 = 12, and finally 12 + 3.5 = 15.5.

What would the temperature be at 35,000 feet if the temperature dropped by 2 degrees for every 1,000 feet of increasing altitude and the temperature at sea level was 25 degrees?

Answer: -45

First, calculate the total altitude increase in thousands of feet: 35,000 feet / 1,000 feet/increment = 35 increments. Since the temperature drops by 2 degrees for every 1,000 feet, the total temperature drop is 35 increments * 2 degrees/increment = 70 degrees. Starting from a sea level temperature of 25 degrees, the temperature at 35,000 feet would be 25 - 70 = -45 degrees.

The value of which of the following is the lowest?

Answer: 1/3 + 3/6

To find the lowest value, evaluate each expression. A) 3 - 10/5 = 3 - 2 = 1. B) 1 - 1/10 = 0.9. C) 4/2 - 3/6 = 2 - 0.5 = 1.5. D) 1/3 + 3/6 = 1/3 + 1/2 = 2/6 + 3/6 = 5/6, which is approximately 0.833. Comparing these values (1, 0.9, 1.5, 0.833), 5/6 is the lowest.

In miles, distance is. According to mass:

Answer: Kilogram

This question is an analogy. Miles are a unit of measurement for distance. Similarly, kilograms are a standard unit of measurement for mass. The other options (Liter, Gravity, Scale) are either units for different quantities or measuring tools, not units of mass.

What is affability's opposite?

Answer: Impoliteness

Affability describes someone who is friendly, good-natured, and easy to talk to. The opposite of being friendly and approachable is being rude or lacking courtesy. Therefore, 'impoliteness' is the most direct antonym, representing a lack of good manners or consideration for others.

Facts: At the bar, the ten pals each ordered one drink. Beer was ordered by half of them. A number of them placed a wine glass order. One made a gin and tonic purchase. A non-alcoholic beverage was consumed by those who chose not to drink a gin and tonic, a glass of wine, or a beer. Conclusion: One customer placed a non-alcoholic beverage order. What is the conclusion based on the evidence? A. The evidence shows that the conclusion is true; B. The evidence shows that the conclusion is false. C. The evidence is insufficient to support or refute the conclusion.

Answer: C

Ten friends ordered drinks: 5 beers and 1 gin and tonic, totaling 6 known orders. This leaves 4 friends who ordered either wine or non-alcoholic beverages. The statement 'A number of them placed a wine glass order' means the number of wine orders could be anywhere from 0 to 4. Consequently, the number of non-alcoholic beverage orders could be 0, 1, 2, 3, or 4. Since the conclusion states exactly 'one customer placed a non-alcoholic beverage order,' and this is only one of several possibilities, the evidence is insufficient to definitively prove or disprove it.

The two figures at the top share a common feature. One of the answer figures lacks the same characteristic. Which figure doesn't have the same trait as the others?

Answer: B

Without the actual figures, a specific explanation cannot be provided. However, in such visual reasoning questions, the common feature often relates to symmetry, the number of elements, rotation, or shading. For example, if figures A, C, and D were all symmetrical along a vertical axis, and figure B was asymmetrical, then B would be the correct answer as it lacks that common trait.
