Find out the wrong number.
4, 9, 19, 43, 90, 185, 376
Correct Answer: Description for Correct answer:
Series follows the pattern
\( \Large 4 \times 2+1=9 \)
\( \Large 9 \times 2+2=20 \)
\( \Large 20 \times 2+3=43 \)
\( \Large 43 \times 2+4=90 \)
\( \Large 90 \times 2+5=185 \)
\( \Large 185 \times 2+6=376 \)
Hence in the question 19 is the wrong number. 19 should be replaced by 20.
