Answer 1

Answer:

Verified

Step-by-step explanation:

Given x,y&z are consecutive terms

=> y = x+1    &  --------------- (1)

   z = x+2        --------------- (2)

we have to prove 2y = x+z

2y = 2(x+1)             (by (1))

    = 2x + 2

    = x+(x+2)

    = x+z                 (by (2))

ie, 2y = x+z

Hence verified
