Find the missing number in the given sequence.

$1, 2, 2, 4, \_\_\_, 4, 2$

Observing the pattern given in the following sequence, identify the missing number in the sequence.

$3,18,219,\_\_\_\_,100005$

What comes in the place of the blanks?

$\mathrm{XXIV},\mathrm{XXII},\mathrm{XXV},\mathrm{XXIII},\mathrm{XXVI},\mathrm{\_\_\_\_},\mathrm{\_\_\_\_}, \mathrm{XXV}$

For finding a number code of $3$ digits, the following information is given:

$\text{ A. }\begin{array}{|lll|}\hline 6& 8& 2\\ \hline\end{array}$ : Only one number is correct and properly placed.

$\text{ B. }\begin{array}{|lll|}\hline 6& 1& 4\\ \hline\end{array}$ : One number is correct but wrongly placed.

$\text{C. }\begin{array}{|lll|}\hline 2& 0& 6\\ \hline\end{array}$ : Two numbers are correct but wrongly placed.

$\text{ D. }\begin{array}{|lll|}\hline 7& 1& 8\\ \hline\end{array}$ : Nothing is correct. 

$\text{ E. }\begin{array}{|lll|}\hline 7& 8& 0\\ \hline\end{array}$ : One number is correct but wrongly placed.

Find the values of ‘$a$’ and ‘$b$’ ?
