Answer:
![4,7,12,19,...](https://tex.z-dn.net/?f=4%2C7%2C12%2C19%2C...)
Step-by-step explanation:
<u><em>The question in English is:</em></u>
From the general term, calculate the first 4 terms.
(Consider that you must assign values to the variable n)
we have
![b_n=n^2+3](https://tex.z-dn.net/?f=b_n%3Dn%5E2%2B3)
step 1
Calculate the first term
For n=1
![b_1=(1)^2+3=4](https://tex.z-dn.net/?f=b_1%3D%281%29%5E2%2B3%3D4)
step 2
Calculate the second term
For n=2
![b_2=(2)^2+3=7](https://tex.z-dn.net/?f=b_2%3D%282%29%5E2%2B3%3D7)
step 3
Calculate the third term
For n=3
![b_3=(3)^2+3=12](https://tex.z-dn.net/?f=b_3%3D%283%29%5E2%2B3%3D12)
step 4
Calculate the fourth term
For n=4
![b_4=(4)^2+3=19](https://tex.z-dn.net/?f=b_4%3D%284%29%5E2%2B3%3D19)
therefore
the first 4 terms are
![4,7,12,19,...](https://tex.z-dn.net/?f=4%2C7%2C12%2C19%2C...)
