Scorpion4ik [409]

Answer:

4,7,12,19,...

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

step 1

Calculate the first term

For n=1

b_1=(1)^2+3=4

step 2

Calculate the second term

For n=2

b_2=(2)^2+3=7

step 3

Calculate the third term

For n=3

b_3=(3)^2+3=12

step 4

Calculate the fourth term

For n=4

b_4=(4)^2+3=19

therefore

the first 4 terms are

4,7,12,19,...
