- The given series is: 86, 74, 84, 76, ?, 78, 80.

- Look at the pattern in the series:

- The first number decreases by 12 (86 to 74).

- The second number increases by 10 (74 to 84).

- The third number decreases by 8 (84 to 76).

- Continuing with this pattern, the next number should increase by 6 (76 + 6 = 82).

- The fifth number decreases by 4 (82 to 78).

- The last number increases by 2 (78 to 80).

- Correct Answer: Option 2 – 82
