Consider the following radioactive decay process
$${ }_{84}^{218} A \xrightarrow{\alpha} A_1 \xrightarrow{\beta^{-}} A_2 \xrightarrow{\gamma} A_3 \xrightarrow{\alpha} A_4 \xrightarrow{\beta^{+}} A_5 \xrightarrow{\gamma} A_6
$$
The mass number and the atomic number of $\displaystyle \mathrm{A}_6$ are given by:
Official answer
From NTA’s final answer key for this paper.
