Two sets of four numbers are given below. In each set of four numbers, a certain mathematical operation on the first number results in the second number. Similarly, a certain mathematical operation on the second number results in the third number and so on.
Which of the options given below follow the same set of mathematical operations?
29 – 841 – 752 – 784
31 – 961 – 872 – 904
Two sets of four numbers are given below. In each set of four numbers, a certain mathematical operation on the first number results in the second number. Similarly, a certain mathematical operation on the second number results in the third number and so on.
Which of the options given below follow the same set of mathematical operations?
29 – 841 – 752 – 784
31 – 961 – 872 – 904
Solution
Let me find the pattern by examining what operations connect the numbers in each given set.
First set: 29 – 841 – 752 – 784
: Check if ✓
: The difference is , so we subtract 89
: The difference is , so we add 32
Second set: 31 – 961 – 872 – 904
: Check if ✓
: The difference is , so we subtract 89
: The difference is , so we add 32
The pattern is: Square → Subtract 89 → Add 32
Now checking each option:
Option 1: 34 – 1156 – 1067 – 1099
| Operation | Calculation | Result | Match? |
|---|---|---|---|
| Square 34 | 1156 | ✓ | |
| Subtract 89 | 1067 | ✓ | |
| Add 32 | 1099 | ✓ |
All three operations match perfectly!
Option 2: 43 – 1849 – 1758 – 1790
✓, but ✗
Option 3: 37 – 1332 – 1243 – 1275
✗
Option 4: 45 – 2025 – 1936 – 1986
✓, ✓, but ✗
Only Option 1 follows all the operations correctly.
