<h2>
Step-by-step explanation:</h2>
If resistors are in series, so the current
is the same in all of them. In this problem we have four resistors. So, we can get a relationship between the Equivalent resistance of series combination and the four resistors as follows:

is the total resistance
. Moreover:

Therefore:
