Question

A partir del término general, calcular los 4 primerostérminos. (Considere que debe asignar

valores a la variable n)
 = 2 + 3

Answer 1

`4,7,12,19,...`

Explanation:

The question in English is:

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,...`
