This Question has 1 answers.
The pattern of the given number series is as:
\n\n→ 1,
\n\n→ 1 × 2 + 2 = 4,
\n\n→ 4 × 2 – 1 = 7, (instead of 8)
\n\n→ 7 × 2 + 2 = 16,
\n\n→ 16 × 2 – 1 = 31,
\n\n→ 31 × 2 + 2 = 64,
\n\n→ 64 × 2 – 1 = 127,
\n\n→ 127 × 2 + 2 = 256,
\n\nHence, the wrong term of the given number series is 8. The correct term is 7.
