Question

The algebric form of an arithmetic sequence is 4n+1
what is its common difference​

Answer 1

Answer:

common difference = 4

Step-by-step explanation:

an = 4n + 1

a1 = 4(1) + 1 = 4 + 1 = 5

a2 = 4(2) + 1 = 8 + 1 = 9

a3 = 4(3) + 1 = 12 + 1 = 13

common difference =

a2 - a1 = a3 - a2

9 - 5 = 13 - 9

4 = 4

therefore the common difference is 4
