Answer:
134217728
Step-by-step explanation:
The geometric sequence formula is:
[tex]\displaystyle{a_n = a_1r^{n-1}}[/tex]
We know that [tex]\displaystyle{a_1=8}[/tex] and [tex]\displaystyle{r=2}[/tex], we also want to find the 25th term, substitute n = 25:
[tex]\displaystyle{a_{25}=8\cdot 2^{25-1}}\\\\\displaystyle{a_{25}=8\cdot 2^{24}}\\\\\displaystyle{a_{25}=134217728}[/tex]
Therefore, the 25th term of sequence is 134217728
