Answer:
4.9%
Step-by-step explanation:
GDP is the growth domestic product of a country over a chosen time period
When the GDP growth rate is reported quarterly , you add together the four quarters for the year to find the annual GDP growth rate.
Given the four consecutive quarters as; 2% , 0.9%, 0.8% and 1.2%
Growth rate for the year will be;

4.9% is the annualized growth rate
You can see how the difference between two consecutive terms is constantly increasing:




So, for the next terms we'll have to add +9, +11, +13 and so on.
Also, note that
is obtained by adding the 2nd odd number to
,
is obtained by adding the 3rd odd number to
, and so on.
So, the recursive formula is

For the explicit formula, recall that the sum of the first n odd numbers is n squared. Taking into account the fact that we're not starting from 1, we have
