The sequence \( \mathrm{a}_{1}, \mathrm{a}_{2}, \mathrm{a}_{3}, \ldots \ldots \mathrm{a}_{98} \) satisfies the relation \( \mathrm{a}_{\mathrm{n}+1}=\mathrm{a}_{\mathrm{n}}+1 \) for \( \mathrm{n}=1,2,3, \ldots \ldots .97 \) and has
P the sum equal to 4949 . Evaluate \( \sum_{\mathrm{k}=1}^{49} \mathrm{a}_{2 \mathrm{k}} \).
