hope it will help

Answer 2

Answer:

The numeric value of the used variable 'x' is - 15.

Step-by-step explanation:

It is given that - 13 , x , -17 are three consecutive term of an AP.

From the properties of arithmetic progressions, we know : -

= > 2 × Middle term = Sum of remaining terms.

Thus,

= >  2 × x = - 13 + ( - 17  )

= >  2x = - 13 - 17

= >  2x = - 30

= >  x = - 30 / 2

= >  x = - 15

Therefore, the numeric value of the used variable 'x' is - 15.
