1.	If in an A.P. the sum of m term is equal to n and the sumof n terms is equal to m, then prove that the sum of (m+n)terms is ‐(m+n).
Answer» Answer: (m+N) -(m+n) so here -m and -n LET us TAKE m as 2 and n as 3 so m+n = 2+3 = 5 -m+-n = -2+-3 = -5 so here 5 is not equal to -5 so it is not possible

If in an A.P. the sum of m term is equal to n and the sumof n terms is equal to m, then prove that the sum of (m+n)terms is ‐(m+n).

Answer»

Answer:

(m+N)

-(m+n) so here -m and -n

LET us TAKE m as 2 and n as 3 so

m+n = 2+3 = 5

-m+-n = -2+-3 = -5

so here 5 is not equal to -5 so it is not possible
