give the answer fast but correct
Answers
Answer:
A=11 is the answer I think
Step-by-step explanation:
Example 1: In the following series, a number is such that it does not belong to the arrangement. Select the option that has this number:
8000, 27000, 64000, 105000
A) 8000 B) 27000 C) 64000 D) 105000
Answer: Focus on the first digit of the numbers. The first digit in each term is a cube of some number except the last option. 105 isn’t the cube of any number, thus the option to select here is D) 105000. The correct entry should be 125000.
Example 2: In the sequence that is present below, one of the terms is missing. Estimate which term is missing and complete the series by selecting it from the options that are present below:
1, 512, 2197, 6859
A) 1, 64, 512, 2197, 6859 B) 1, 512, 1331, 2197, 6859 C) 1, 512, 2197, 4913, 6859 D) 1, 216, 512, 2197, 6859
Answer: Here the series has been given but we are not told where the missing number has to go. This makes it a bit more difficult than the other series. But since this is a cube series, we can still predict the number easily. if you take a look at the table of cubes that we wrote above, you will see that the series can be written as follows:
13, 83, 133, 193. Thus the pattern is clear. The first term is the cube of 1 and then the rest of the terms are cubes of 8, 13, and 19. The difference between 13 and 8 is 5 and that between 19 and 13 is 6. Thus there should be a term between 1 and 8 whose difference from 8 is 4 and from 1 is 3. This term is 4 and the cube of 4 is 64. Thus the correct series is A) 1, 64, 512, 2197, 6859.
