Answer 2

`a_(50)=16`

Explanation:

Given that,

An airthmetic sequence,

261,256,251

We need to find the 50th term.

We have,

first term, a = 261

common difference = 256-261 = -5

The nth term of the AP is given by :

`a_n=a+(n-1)d\\\\a_(50)=a+49d\\\\a_(50)=261+49(-5)\\\\a_(50)=16`

So, the 50th term of the sequence is 16.
