Correct Answer: 8 : 56 : 3100
Solution : Let's check the options – First option: 3 : 21 : 147→3 × 7 = 21; 3 × 49 = 147 Second option: 8 : 56 : 3100→8 × 7 = 56; 8 × 49 = 392 ≠ 3100 Third option: 1 : 7 : 49→1 × 7 = 7; 1 × 49 = 49 Fourth option: 10 : 70 : 490→10 × 7 = 70; 10 × 49 = 490
So, the second option does not follow the pattern of the other three options. Hence, the second option is correct.
