2. (8 points) Zhang Jie wrote 26 consecutive odd numbers starting from 27, while Wang Qiang wrote 26 consecutive natural numbers starting from 26. Then they each found the sum of the 26 numbers they wrote. What is the difference between these two sums? $\qquad$ RMB.
【Solution】Solution: According to the analysis, the 26 consecutive odd numbers starting from 27 are: $27,29,31,33,35 \cdots$, it is not difficult to observe that these 26 odd numbers form an arithmetic sequence with a common difference of 2. The sum of these 26 odd numbers $=26 \times 27+\frac{1}{2} \times 26 \times 25 \times 2=1352$;

The 26 consecutive natural numbers starting from 26 are: $26,27,28,29,30 \cdots$,
it is not difficult to observe that these 26 natural numbers form an arithmetic sequence with a common difference of 1. The sum of these 26 consecutive natural numbers $=26 \times 26+\frac{1}{2} \times 26 \times 25 \times 1=1001$, difference: $1352-1001=351$.

Therefore, the answer is: 351.
