Which recursive formula can be used to represent the sequence 2,6,10,14, !

The first term = 2

a1 = 2

a_n=a_{n-1}+4

Step-by-step explanation:

We have the sequence 2, 6, 10, 14, 18, ... Always 4 being added, so we can say:

The first term is 2. The added is 4, so,

a1 = 2

Prove:

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25
