Option 3: 16, 12, 14
Option 4: 14, 11, 13
Correct Answer: 14, 11, 13
Solution : Let's check each option –
First option:
20, 16, 18→20 – 4 = 16; 16 + 2 = 18
Second option:
18, 14, 16→18 – 4 = 14; 14 + 2 = 16
Third option:
16, 12,14→16 – 4 = 12; 12 + 2 = 14
Fourth option:
14, 11, 13→14 – 3 = 11; 11 + 2 = 13
So, the fourth option is different as the difference in the first and the second term is 3 instead of 4. Hence, the fourth option is correct.
