. The first term of an arithmetic sequence is 4 and the tenth term is 67.
What is the common difference? Show your work or explain your answer.

           d=7

Step-by-step explanation:

it is arithmetic sequence

so we will use this equation to get d (common difference)

a(n) = a1 +(n-1)d

we have the tenth term=67  and a1 =4

then

a(10) = 4 +(10-1)d=67

          4+10d-1d=67

          9d=67-4

          9d=63 dividing by 9

           d=7

hope this helps

if you are looking for the unit rate then the answer would be 9 because unit rate is distance divided by time.

step-by-step explanation:

(x) - (y) = (1 + 4i)
