xxMikexx [17]

Answer: (2.5  ;  1.5 )

Step-by-step explanation:

  • The midpoint of the segment with the points \bf  ( x_1  \ ;  \ y_ 1) and \bf (x_2 \  ;  \ y_2)  is calculated by the formula:

  • \bf (x _0  \ \ ;  \ \ y _0) = \bigg(\dfrac{x_1+x_2}{2} \ ; \  \dfrac{y_1+y_2}{2}  \bigg)  
  • Then :
  • \bf (x_0 \  ;  \ y_ 0)=\bigg( \dfrac{3+2}{2}  \ \ ;  \dfrac{4-1}{2}  \bigg)  =( 2.5  \  \ ; \ \  1,5 )

Which term of a AP 5 , 13 , 21 ,... is 181?
Sauron [17]
Here,a(n) =  a + (n-1)d
Here, a = 5, d = 12-5 = 8, a(n) = 181
Substitute this values in to the expression,

181 = 5 + (n-1)8
181-5 = 8n-8
176+8 = 8n
n = 184/8
n = 23

So, it is 23th term of that Arithmetic Progression.

Hope this helps!
