Fill in the blank : 4, 12, 6, 18, 19, __________

Given series:

4, 12, 6, 18, 19, ?

Observe the pattern carefully.

The series follows alternating operations:

• $4 \times 3 = 12$
• $12 \div 2 = 6$
• $6 \times 3 = 18$
• $18 + 1 = 19$

Now continue the multiplication pattern:

$19 \times ?$

Among the options, the suitable continuation is:

$19 + 8 = 27$

So the intended pattern is likely:

$+8,\div2,\times3,+1,+8...$

Hence,

19 + 8 = 27

Correct Answer: 27
