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

✅ Correct Option: 1

Let me find the pattern by examining what operations connect the numbers in each given set.

First set: 29 – 841 – 752 – 784

29→84129 \to 841: Check if 292=84129^2 = 841 ✓

841→752841 \to 752: The difference is 841−752=89841 - 752 = 89, so we subtract 89

752→784752 \to 784: The difference is 784−752=32784 - 752 = 32, so we add 32

Second set: 31 – 961 – 872 – 904

31→96131 \to 961: Check if 312=96131^2 = 961 ✓

961→872961 \to 872: The difference is 961−872=89961 - 872 = 89, so we subtract 89

872→904872 \to 904: The difference is 904−872=32904 - 872 = 32, so we add 32


The pattern is: Square → Subtract 89 → Add 32

Now checking each option:

Option 1: 34 – 1156 – 1067 – 1099

Subtract 891156−891156 - 891067✓
Add 321067+321067 + 321099✓

All three operations match perfectly!

Option 2: 43 – 1849 – 1758 – 1790

432=184943^2 = 1849 ✓, but 1849−89=1760≠17581849 - 89 = 1760 \neq 1758 ✗

Option 3: 37 – 1332 – 1243 – 1275

372=1369≠133237^2 = 1369 \neq 1332 ✗

Option 4: 45 – 2025 – 1936 – 1986

452=202545^2 = 2025 ✓, 2025−89=19362025 - 89 = 1936 ✓, but 1936+32=1968≠19861936 + 32 = 1968 \neq 1986 ✗

Only Option 1 follows all the operations correctly.
