Question

Find the wrong term of the series :

$6,8,9,12,14,18,22,26,30$

• A. $12$
• B. $22$
• C. $26$
• D. $30$

Answer 1

Answer: (B)

$22$

The given series: 6, 8, 9, 12, 14, 18, 22, 26, 30 consists of two series.
1st series: 6, 9, 14, 22, 30 2nd series: 8, 12, 18, 26
In the 1st series, the difference between the terms is as: +3, +5, +7 and +9.
In the 2nd series, the difference between the terms is as: +4, +6, +8.
Clearly, 14 + 7 = 21.
So, 22 is the wrong term.
Hence, option (B) is the correct answer.
