The logic followed here is the first number is multiplied by 7 and then 7 is subtracted from the obtained number to get the second number. 42 - 287 = (42 X 7) – 7 = 294 - 7 = 287; 287 = 287 70 - 450 = (70 X 7) – 7 = 490 - 7 = 483; 483 ≠ 450 25 – 168 = (25 X 7) – 7 = 175 - 7 = 168; 168 = 168 52 - 357 = (52 X 7) – 7 = 364 - 7 = 336; 336 = 357
