Step-by-step explanation:
The coefficient of determination = 
= 0.7832
It means about 78% variation in waist size of males can be explained by their weight and about 23% can not be explained.
Arithmetic sequence: must have a constant common difference.
3/20-1/10=(3-2)/20=1/20
5/30-3/20=(10-9)/60=1/60
Difference is not constant, so no.
Geometric sequence: must have a common ratio
30/20 / (1/10) = 15
5/30 / (3/20) = 100/90 = 10/9
ratio is not constant, so no.
The answer is (c) neither geometric nor arithmetic

Exponents first
= 2*16 -5*4
Multiply
=32 -20
subtract
=12
