17th term of the A.P. 13, 16, 19, 22, 25, ..... is :

The correct answer is Option (3) → 61

In an A.P. each term is the previous one plus the common difference \(d\), so the \(n\)th term is \(a_n=a+(n-1)d\).

• First term \(a=13\); common difference \(d=16-13=3\)

• 17th term: \(a_{17}=13+16\times3=13+48=61\)
