Question

find the common difference and write the next three terms of the A.P.
3,-2,-7,-12​

Answer 1

Answer:

-5

Step-by-step explanation:

a=3

A2 =-2

d=A2 -a

d=-2 -3

d=-5

Answer 2

$\huge\underline\mathfrak{Solution}$

d = $a_2$ - $a$

- 2 - 3 = d

Common difference = -5

____________________

Next three terms :

-12 + (-5) = -17

-17 + (-5) = -22

-22 + (-5) = -27

Therefore, next three terms are -17,-22,-27..
