not sure how to solve this..38^(n+3) +2 divided by 5, has remainders all over the place

i am only focusing on the unit digit of 38, which is determined by 8, unit digits are 2, 6, 4 etc +2 =4, 8, 6, which give remainder 4, 3, and 1

If question is asking to find the remainder when 38^(n+3) +2 is divided by 5
then there is no single answer

Put n=1, then unit digits of 38^4 =6. then the unit's digit of the number =8.Therefore, the remainder would be 3

put n=2, unit digits of 38^5=8, then unit digits of the number=0. therefore there would be no remainder.
