What will be the last term in the AP of positive multiples of (29) less than (2500)?

Answer and explanation

Correct answer: 2494

The positive multiples of 29 form the AP \(29, 58, 87, \ldots\), whose \(n\)th term is \(29n\). For the last term, \(29n<2500\). Since \(2500\div29\approx86.2\), the greatest integer value of \(n\) is 86. Hence the last term is \(29\times86=2494\). Although \(2523=29\times87\), it is greater than 2500. Exam tip: for “less than”, use the integer part of the quotient and verify the product.
