Answer 2

The 31th term of the given A.P. is 40

Step-by-step explanation:

Given : -50 , -47, -44 is an A.P.

To find: The 31th term

Therefore

nth term of an A.P. is given by

$a_n=a+(n-1)d$

where $a_n$ is the nth term, a is first term , n is number of terms and d is common difference

So in given A.P.  we have a= -50 , d= -47-(-50) = -47+50 = 3

Therefore

$a_{31}= -50+ (31-1)(3)\\\\\Rightarrow a_{31} = -50+ 30 \times 3= -50+90 = 40$

Hence the 31th term of the given A.P. is 40
