Answer:

Step-by-step explanation:
We are given;
A geometric sequence;
 -2,10,-50
Required to determine the nth term 
The nth term in a geometric sequence is given by the formula;

where  is the first term and r is the common ratio;
 is the first term and r is the common ratio;
In this case;

r = 10 ÷ -2
   = -5
Therefore;
To get the nth term in the given geometric sequence we use;

Thus, the nth term is

Answer:
Using the calculator angle whose cos  is 0.9511 is  18 degrees
Sine of the complementary angle = 0.9511 also
Step-by-step explanation:
The sine of the complementary angle( which is 90-18 = 72 degrees) is same value  0.9511
