Select the set in which the numbers are related in the same way as are the numbers of the following sets. (Note: Operations should be performed on the whole numbers, without breaking down the numbers into their constituent digits. E.g. 13 – Operations on 13 such as adding/subtracting/multiplying to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.) (163, 186, 23) (144, 200, 56)
(113, 178, 65)
In each set the third number is the difference between the second and the first number.
First set: 186 - 163 = 23. Second set: 200 - 144 = 56. Both match.
Test the options: for (113, 178, 65), 178 - 113 = 65, which matches the third number.
Checking the others: 229 - 141 = 88 (not 98), 187 - 135 = 52 (not 62), 243 - 201 = 42 (not 43).
Hence, the set that follows the same rule is (113, 178, 65).
