Answer:
During the 1950s and early 1960s many Americans retreated to the suburbs to enjoy the new consumer economy and search for some normalcy and security after the instability of depression and war.

King Alaric is a well-known figure in the Sack of Rome. He led the Visigoths and infiltrated Rome. He was elected the Chief of Visigoths and iterated that his people were not getting enough subsidies to live by.
After leading his people into several successful as well as unsuccessful heists, he finally sacked the western part of Rome. This event was marked as one of the most important events in history as it was the defeat of Western Rome after centuries.
Answer:
From the first generation = 2 ancestors.
From the second generation = 4 ancestors or (2)^2 ancestors.
From the third generation = 8 ancestors or (2)^3 ancestors.
We can infer from the given data, each consecutive generation possesses twice the number of members.
The sum will be:
2 + 4 + 8 + 16 + ... + (2)^39
To evaluate the amount of ancestors, let's employ the formula for the summation of a geometric sequence.
(Geometric sequence shows the sequence of numbers that varies by a specific factor. This factor is specifically known as a ratio).
Formula for Geometric sequence:
S = (a1) × 1 - (r)^n
--------------------------
1 - r
Take:
S -> sum
a1 -> first member of a sequence
r -> ratio
n -> number of elements
In this question, our:
a1 = 2; r = 2; and n = 39
S = (2) × 1 - (2)^39
-------------------------
1 - 2
S = 1,099,511,627,777
