For the Paschen series the values of $\mathrm{n}_1$ and $\mathrm{n}_2$ in the expression $\Delta E=R h c\left(\frac{1}{n_1^2}-\frac{1}{n_2^2}\right)$ are

• A

  $\mathrm{n}_1=1, \mathrm{n}_2=2,3,4 \ldots \ldots$
• B

  $\mathrm{n}_1=2, \mathrm{n}_2=3,4,5 \ldots \ldots$
• Correct answer
  C

  $\mathrm{n}_1=3, \mathrm{n}_2=4,5,6 \ldots \ldots$
• D

  $\mathrm{n}_1=4, \mathrm{n}_2=5,6,7 \ldots \ldots$

Hence, the correct answer is option: 'C'.
