Concept:The given sequence increases by the same value each time, so it is an arithmetic progression.Explanation:First term is a=3.Common difference is d=8−3=5.The general term of an arithmetic progression is given by Tn=a+(n−1)d.Substitute a=3 and d=5:Tn=3+(n−1)5.Expand the bracket:Tn=3+5n−5.Collect like terms:Tn=5n−2.Verification: For n=1, T1=5(1)−2=3. For n=2, T2=5(2)−2=8. This matches the sequence.Answer:Option A: 5n−2
