Step-by-step explanation:
Given:if 8x+7,15,2x-7 are the three consecutive terms of A.P.
To find:find the value of x .write algebric sequence.
Solution:
As given terms are three consecutive terms of A.P., so to find the value of x.
Calculate the common difference and thus solve for the value of x
Common difference d:Second term-first term
Also
Common difference d: Third term-Second term
Compare these two equations
Thus,
value of x is 3.
Algebraic sequence is
Thus,
The Algebraic sequence is
31,15,-1
