Total questions = 10

Let a be the marks for the first question.

Then the marks for 10 questions in order are a, a+4, a+8,....a+36

This is an arithmetic sequence with common difference d =4

Sum of 10 terms =

This sum is given as 360

Equating we get

Hence III question will have points as 18+2(4) = 26.
