$\sf{ \bold{ \green{let \: us \: write \: the \: given \: }{} }{} }{}$

Given that a =4 That's is First term is 4

The number of terms n = 7

The last term which is = 4

It is required to find the value of d

From the equation

an = a+(n-1)d

Insert the given

4=4+(7-1)d

4-4 = 6d

0 = 6d

d = 0/6

d = 0

so, the ap is

4,4,4,4,4,4,4,

$\sf{ \bold{ \purple{d \: = 0}{} }{} }{}$
