In an arithmetic sequence, the 23rd term is \(\frac{1}{4}\) and the 35th term is \(\frac{2}{5}\). What is the 48th term?

1/4  + 12d = 2/5

 

12d = 2/5 -1/4

 

12d =  3/20

 

d =  3/20 * 1/12  =  1/80

 

2/5 + 13d =  48th term

 

2/5 + 13 ( 1/80)  = 

 

[ 32]/80 + [13]/80  = 

 

45 / 80  = 

 

9 / 16
