Find the first five terms of the sequence.
a(n)= 3/5

               a(n) = 3/5

I'm sorry if this is not what you're expecting.  But that equation says that
the value of the term doesn't depend on where it is in the sequence ...
on 'n' .

Every term is the same number.  No matter what 'n' may be, the value of 
a(n)  is always 3/5. 

The first five, fifty, five hundred, or five thousand terms are all  3/5 .

Answer: d. 39 cmin the diagram, the approximate length of the minor arc de is 39 centimetres.step-by-step explanation: the formula for the length of an arc in a circle is as displayed below.let the length of the minor arc de = xx = 2( pi )r × angle of sector / 360°from this, we will substitute the values given from the problem into the formula to obtain the length of the minor arc de.x = 2( pi )r × angle of sector / 360°r = radius = 25cmpi as an approximate value = 3.14angle of sector = 120°x = 2( 3.14 )( 25 ) × 120° / 360°x = 157 × 1 / 4x = 39.25x = 39 ( rounded to the nearest whole number as an approximate value )
