x=45.45454545
Answer:
588245.
Step-by-step explanation:
nth term = an = a1 r^(n-1) where a1 = the first term
a3 = 35 = a1 7^(3 - 1)
35 = a1* 49
a1 = 35/49 = 5/7
So the 8th term = (5/7)* (7)^7
= 588245

<em>cos(2x/3+Pi/4)=cos pi/4
</em>
<em>2x/3+pi/4=pi/4+k2pi or 2x/3+pi/4 =-pi/4+

<em>k2pi X=K3pi or x=-3pi/4 + k3pi</em>
