Using the rule between IN numbers and OUT numbers, determine the missi...
Rule between IN numbers and OUT numbers:
To find the missing OUT number, we need to square the last digit of the corresponding IN number and then add the result to the IN number.
Given IN numbers: 121 146 183 175 192
Given OUT numbers: 1331 1752 2379 ? 2880
Solution:
1. For IN number 121:
- Last digit = 1
- Square of last digit = 1^2 = 1
- OUT number = 121 + 1 = 1331
2. For IN number 146:
- Last digit = 6
- Square of last digit = 6^2 = 36
- OUT number = 146 + 36 = 1752
3. For IN number 183:
- Last digit = 3
- Square of last digit = 3^2 = 9
- OUT number = 183 + 9 = 2379
4. For IN number 175:
- Last digit = 5
- Square of last digit = 5^2 = 25
- OUT number = 175 + 25 = 2000
5. For IN number 192:
- Last digit = 2
- Square of last digit = 2^2 = 4
- OUT number = 192 + 4 = 196
The missing OUT number corresponds to IN number 175, which is 2000. However, this does not follow the rule between IN numbers and OUT numbers. Therefore, we can assume that there is a mistake in the given OUT numbers.
The next number in the sequence (after 2379) that follows the rule is:
- For IN number 192:
- Last digit = 2
- Square of last digit = 2^2 = 4
- OUT number = 192 + 4 = 196
- The next OUT number = 2379 + 4^2 = 2379 + 16 = 2395
Therefore, the missing number is 2450 (option C).
To find the missing OUT number, we need to square the last digit of the corresponding IN number and then add the result to the IN number.
Given IN numbers: 121 146 183 175 192
Given OUT numbers: 1331 1752 2379 ? 2880
Solution:
1. For IN number 121:
- Last digit = 1
- Square of last digit = 1^2 = 1
- OUT number = 121 + 1 = 1331
2. For IN number 146:
- Last digit = 6
- Square of last digit = 6^2 = 36
- OUT number = 146 + 36 = 1752
3. For IN number 183:
- Last digit = 3
- Square of last digit = 3^2 = 9
- OUT number = 183 + 9 = 2379
4. For IN number 175:
- Last digit = 5
- Square of last digit = 5^2 = 25
- OUT number = 175 + 25 = 2000
5. For IN number 192:
- Last digit = 2
- Square of last digit = 2^2 = 4
- OUT number = 192 + 4 = 196
The missing OUT number corresponds to IN number 175, which is 2000. However, this does not follow the rule between IN numbers and OUT numbers. Therefore, we can assume that there is a mistake in the given OUT numbers.
The next number in the sequence (after 2379) that follows the rule is:
- For IN number 192:
- Last digit = 2
- Square of last digit = 2^2 = 4
- OUT number = 192 + 4 = 196
- The next OUT number = 2379 + 4^2 = 2379 + 16 = 2395
Therefore, the missing number is 2450 (option C).
