Geometric sequence 5

About members of geometric sequence we know:

3 a<sub>5</sub>:a<sub>3</sub> = 27:25 ; ;
7 a<sub>3</sub> +5 a<sub>7</sub> = 1 : 564 ; ;

Calculate a1 (first member) and q (common ratio or q-coefficient)


Result

q =  0.6
a1 =  204.84658

Solution:

Solution in text q =
Solution in text a__1 =
