Step-by-step explanation:
Given the A.P series
-6, -4, -2, 0, ...
we have to find the thirtieth term of the following sequence.
The A.P is -6, -4, -2, 0, ...
which implies
Common difference, d=-4-(-6)=-4+6=2
First term=a=-6
n=30
hence, the thirtieth term of sequence is 52

Answer: After 7 years the population will be one-half the initial amount.
Step-by-step explanation:
Given: Initial population = 500,000
The population declines according to the equation:
, where P is the population in t years later.
One-half the initial amount = 0.5 x 500,000
= 250,000
Put P(t)=250,000, we get
Hence, After 7 years the population will be one-half the initial amount.
