The number is increasing by 2 every time.
78 x 2 = 156
-4 + 156 = 152
The 78th term is 152
Answer:

Step-by-step explanation:
Let the numbers be x,y, where x>y
The geometric mean is

The Arithmetic mean is

The ratio of the geometric mean and arithmetic mean of two numbers is 3:5.

We can write the equation;

or

l
and

or

Make y the subject in equation 2

Put equation 3 in 1





When x=1, y=10-1=9
When x=9, y=10-9=1
Therefore x=9, and y=1
The ratio of the smaller number to the larger number is

Answer:
x = 31 degrees
Step-by-step explanation:
180 - 149 = 31
