Question

if 4 by 5 , a , 2 are three consecutives terms of an AP , what is the value of a

Answer 1

Answer:

Step-by-step explanation:

Three consecutive terms in AP Middle term is mean of other two

A=1/2(4/3+2) =1/3

Answer 2

The common difference between consecutive terms is a constant. Therefore let the common difference be k.

k = 2 - a 

k = a - 4/5 

2 - a = a - 4/5 

2a = 14/5 

a = 7/5 

Therefore, a = 7/5
