Sagot :

Answer:

11 , 15 , 19 , 23 , 27

Step-by-step explanation:

given the position to term rule is multiply by 4 then add 7 , that is

4n + 7 ( n is the term position )

To find the first 5 terms, substitute n = 1, 2 , 3 , 4 , 5 into the rule

n = 1 : 4(1) + 7 = 4 + 7 = 11

n = 2 : 4(2) + 7 = 8 + 7 = 15

n = 3 : 4(3) + 7 = 12 + 7 = 19

n = 4 : 4(4) + 7 = 16 + 7 = 23

n = 5 : 4(5) + 7 = 20 + 7 = 27

The first 5 terms are 11 , 15 , 19 , 23 , 27
