Answer:
First term a₁ = 3/2 and common ratio r = 2
Step-by-step explanation:
We need to find the first term and common ratio while we are given third term = 6 and seventh term = 96
Since common ratio is required so, the sequence is geometric sequence
The formula used is: 
We are given: third term = 6 i,e

Seventh term = 96

Dividing eq(2) and eq(3)

So, Common Ratio r = 2
Finding First term using eq(1)

So, First term a₁ = 3/2 and common ratio r = 2
Answer:
3,-3,5,-3, the second and fourth are the same
Step-by-step explanation:
AD and FC are perpendicular so they make a 90 degree angles. Angle BDC is equal to angle FDE so its 25. then u take 90 and subtract 25 to find the anser your looking for... so its 65
