Question

In an a Arithmatic progression the 3rd term is 3 and 5th term is -11 find the 50th term​

Answer 1

Answer:

-326

Step-by-step explanation:

Here we have to mainly use the formula

" tn = a+(n-1)d"

Hence , first equation we get ,

3= a + (3-1)d

i.e 3 = a+ 2d

second equation we get ,

-11= a + 4d

on solving both equation simultaneously , we get

a = 17 and d = -7

therefore,

t50 = 17 + (50-1)(-7)

= 17 + (-343)

= -326
