Find the nth term of this quadratic sequence 4 7 12 19 28

Mathematics
1 answer:
Elis [28]3 years ago

Answer: 84


Step-by-step explanation:

from 4 to 7 , they added 3

from 7 to 12 they added 5

from 12 to 19 they added 7

from 19 to 28 they added 9

3, 5, 7, 9.... They are simply adding odd numbers to each number. So after 9 would be 11, so you add 11 to 28 and get 39, and so on...

39 + 13= 52

52 + 15 = 67

67 + 17 = 84

84 is the ninth term, so that is your answer.

what is the economic and political system in which the government controls property and the distribution of income? in this syst
Nutka1998 [239]

Let's look over the meaning of each option:


Theocracy: Theo- means that it is relating to religion. For example, Theology is the study of religion. This is a system where religious leaders control the country, but it is NOT an economic system.

Monarchy: Monarchy is when there is a king, queen, emperor, etc. It is not an economic system either.

Fundamentalism: A political system that strictly abides by a set of fundamentals. Someone who wants a constitution to be the highest form of law is a fundamentalist. However, this is also not an economic system.

Socialism: WINNER WINNER CHICKEN DINNER! Socialism is a system similar to communism where the government controls the economy and there is communal ownership. This is also the only option which is both a political and economic system.


TL;DR: The answer is Socialism.
