6, 7, 12, 26, ?, 205.5a)57.5b)47.5c)67.5d)37.5e)27.5Correct answer is ...
6 * 1 + 1 = 7
7 * 1.5 + 1.5= 12
12 * 2 + 2 = 26
26 * 2.5 + 2.5 = 67.5
67.5 * 3 + 3 = 205.5
7 * 1.5 + 1.5= 12
12 * 2 + 2 = 26
26 * 2.5 + 2.5 = 67.5
67.5 * 3 + 3 = 205.5

6, 7, 12, 26, ?, 205.5a)57.5b)47.5c)67.5d)37.5e)27.5Correct answer is ...
Given sequence: 6, 7, 12, 26, ?, 205.5
To find the missing number (?), we need to identify the pattern followed in the given sequence.
Pattern:
- The difference between 7 and 6 is 1.
- The difference between 12 and 7 is 5.
- The difference between 26 and 12 is 14.
- The difference between ? and 26 is 24.
- The difference between 205.5 and ? is 179.5.
From the above pattern, we can observe that the differences between the consecutive terms in the sequence are increasing by odd numbers.
Using this pattern, we can find the missing number as follows:
- The difference between 26 and the missing number is 24. So, the missing number should be 26+24 = 50.
- The difference between 205.5 and 50 is 155.5. So, the next term in the sequence should be 205.5+155.5 = 361.
Therefore, the missing number in the given sequence is 50, and the next term in the sequence is 361.
But, none of the given options is equal to 361. So, we need to find another way to solve this problem.
Alternative approach:
We can also find the missing number by identifying the ratio between the consecutive terms in the sequence.
- The ratio between 7 and 6 is 7/6.
- The ratio between 12 and 7 is 12/7.
- The ratio between 26 and 12 is 26/12 = 13/6.
- The ratio between ? and 26 is ?/26.
- The ratio between 205.5 and ? is 205.5/?.
From the above ratios, we can observe that the ratio between the consecutive terms in the sequence is increasing by a factor of (7/6).
Using this pattern, we can find the missing number as follows:
- The ratio between 26 and the missing number is (7/6)^2 = 49/36. So, the missing number should be (49/36)*26 = 35.88888... ≈ 35.89.
- The ratio between 205.5 and 35.89 is (7/6)^4 = 2401/1296. So, the next term in the sequence should be (2401/1296)*205.5 = 380.25.
Therefore, the missing number in the given sequence is 35.89, and the next term in the sequence is 380.25.
But, none of the given options is equal to 380.25. However, option (C) is the closest to 380.25, as 67.5*5.625 ≈ 379.69. So, the correct answer is option (C) 67.5.
To find the missing number (?), we need to identify the pattern followed in the given sequence.
Pattern:
- The difference between 7 and 6 is 1.
- The difference between 12 and 7 is 5.
- The difference between 26 and 12 is 14.
- The difference between ? and 26 is 24.
- The difference between 205.5 and ? is 179.5.
From the above pattern, we can observe that the differences between the consecutive terms in the sequence are increasing by odd numbers.
Using this pattern, we can find the missing number as follows:
- The difference between 26 and the missing number is 24. So, the missing number should be 26+24 = 50.
- The difference between 205.5 and 50 is 155.5. So, the next term in the sequence should be 205.5+155.5 = 361.
Therefore, the missing number in the given sequence is 50, and the next term in the sequence is 361.
But, none of the given options is equal to 361. So, we need to find another way to solve this problem.
Alternative approach:
We can also find the missing number by identifying the ratio between the consecutive terms in the sequence.
- The ratio between 7 and 6 is 7/6.
- The ratio between 12 and 7 is 12/7.
- The ratio between 26 and 12 is 26/12 = 13/6.
- The ratio between ? and 26 is ?/26.
- The ratio between 205.5 and ? is 205.5/?.
From the above ratios, we can observe that the ratio between the consecutive terms in the sequence is increasing by a factor of (7/6).
Using this pattern, we can find the missing number as follows:
- The ratio between 26 and the missing number is (7/6)^2 = 49/36. So, the missing number should be (49/36)*26 = 35.88888... ≈ 35.89.
- The ratio between 205.5 and 35.89 is (7/6)^4 = 2401/1296. So, the next term in the sequence should be (2401/1296)*205.5 = 380.25.
Therefore, the missing number in the given sequence is 35.89, and the next term in the sequence is 380.25.
But, none of the given options is equal to 380.25. However, option (C) is the closest to 380.25, as 67.5*5.625 ≈ 379.69. So, the correct answer is option (C) 67.5.
