You've exchanged the emission factors from oil, coal and gas.
You don't use the right way to calculate the average annual percentage growth.
If you have an annual growth of p percent, and initial emission $E_i$ the emission in 26 years will be:
$$E_i (1+\frac {p} {100})^{26}$$

Can you find p from that?​
