Question
Select the option in which the numbers are related in
the same way as are the numbers of the following set. (285, 313, 299)Solution
The logic followed here is as follows, From the left end, (First number + Second number) ÷ 2 = Third number. (285, 313, 299) → (285 + 313) ÷ 2 = 598 ÷ 2 = 299. (315, 267, 294) → (315 + 267) ÷ 2 = 582 ÷ 2 = 291 ≠294. (142, 244, 205) → (142 + 244) ÷2 = 366 ÷ 2 = 183 ≠205. (443, 251, 347) → (443 + 251) ÷ 2 = 694 ÷ 2 = 347 (534,222, 381) → (534 + 222) ÷2 = 756 ÷ 2 = 378 ≠381.
