In the following number series, two numbers have been put within brackets. Select the most appropriate option for these numbers in relation to their inclusion in the series.

1, 5, 17, (39), 65, 101, (145), 197

The first bracketed number from the left is incorrect and the second bracketed number from the left is correct.

1   2    3    4   5    6   7     8    9  10  11  12  13

 A   B   C    D   E    F   G    H    I    J    K    L   M

 ↓    ↓    ↓    ↓    ↓     ↓   ↓    ↓     ↓   ↓    ↓    ↓    ↓

 Z   Y    X   W   V    U   T    S    R   Q   P    O   N

26  25  24  23  22  21  20  19  18  17  16  15  14

**********************************************************

THE LOGIC FOLLOWED HERE IS :

1, 5, 17, (39), 65, 101, (145), 197

(The difference between the numbers are 8)

1 → (+4) → 5

5 → (+12) → 17    (difference between 4 to 12 is 8)

17 → (+20) → 37    (difference between 12 to 20 is 8)

37 → (+28) → 65      (difference between 20 to 28 is 8)

65 → (+36) → 101    (difference between 28 to 36 is 8)

101 → (+44) → 145    (difference between 36 to 44 is 8)

145 → (+52) → 197    (difference between 44 to 52 is 8)

Thus,

(39) is incorrect and 37 is correct number which has to be in the first bracket, not (39)

Thus, The first bracketed number from the left is incorrect and the second bracketed number from the left is correct.
