Question

If an A.P. is 10, 7, 4, ....., -62, find the 11th
term from its end. ​

Answer 1

Answer:

answer for the given problem is given

Answer 2

fact:- when we find common difference from the end the sign will be change

common difference =7-10 = -3 sign will be change

D = 3

AP from end the first term will be - 62

a11 = a1+10d

= -62+30= -32

hence AP from the end of 11th term will be -32
