Question

If an=n(n-3)/n+4,then find the 18th term of this sequence

Answer 1

Answer:

Given:

$\large{An=n(n-3)/n+4}$

To find:

18th term

$\large{Answer}$

put n=18

so we get

$a(18) = \frac{18(18 - 3)}{18} + 4$

$a(18) = \frac{18 \times 15}{18} + 4$

$a(18) = \frac{270}{18} + 4$

$a(18) = 15 + 4$

$a(18) = 19$
