Question

Is 101 a term of the arithmetic sequence 3, 7, 11,.....? What about 103? ​

Answer 1

Answer:

103 is a term but 101 is not

Step-by-step explanation:

3 , 7 ,11

a = 3

d = 4

101 = 3 + (n - 1)4

101 = 3 + 4n - 4

102 = 4n

n = 25.5

101 is not a term

103 = 3 + (n - 1)4

103 = 3 + 4n - 4

104 = 4n

n = 26

103 is a term
