Answer:

Step-by-step 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 :

So, the 50th term of the sequence is 16.
It’s -1/3 because you subtract 1-5 and -3-9, you get -4/-12 then simplify to get -1/3.
The length of a segment, given the extremities, is:
√[(x₂ - x₁)² + (y₂ - y₁)²]
Therefore:
RS = √[(3-1)² + (1-3)²] = √(4+4) = √8
RT = √[(5-1)² + (2-3)²] = √(16+1) = √17
ST = √[(5-3)² + (2-1)²] = √(4+1) = √5
Since the lengths are all different, the triangle is scalene.
