Concept:In an arithmetic sequence, each term is found by adding the same number (the common difference d) to the term before it.Solution:Find d from known consecutive terms:−5−(−9)=−5+9=47−3=4 and 11−7=4, so d=4.m comes right after −5:m=−5+4=−1Check: the next term should be m+4=−1+4=3, which matches the given term ✓.Answer:Option B (−1)
