Question

Find the missing term in the series given below. $12,13,18,19,24,25$?

• A. $27$
• B. $30$
• C. $29$
• D. $26$

Answer 1

The correct option is B $30$

$12,13,18,19,24,25$

difference between $12,13=1$

difference between $13,18=5$

Similarly

difference between $18,19=1$

difference between $19,24=5$

similarly

difference between $24,25=1$

so to get next number of $25$ add $5$ i.e., $25+5=30$
