Question

Find the two middle terms of an AP-4/3,-1,-2/3...............,4 *1/3

Answer 1

Answer:

Step-by-step explanation :

a+(n-1)d =4/3

-4/3+n-1x1/3 = 4/3

n-1 = 8/3/1/3= 8

n=9

Since the terms are in odd no

The middle term is n+1/2 th term

ie 9+1/2 th term ie 5th term

Therefore the middle term is

a+4d = -4/3+4*1/3=0

Note : The question that you have been asked contains two middle terms , therefore you can take the 6 th term also ie a +5d = -4/3+5*1/3= 1/3
