Step-by-step explanation:
median is the value in middle
low from high:
168800
172200
174500
177600
183700
191400
174500 and 177600 is the middle.
174500 + 177600 = 352100
352100/2 = 176050

Answer:
First term (a) =8
Common difference (d)= t2-t1
 =12-8
 =4
Now, sum of first 31th term (tn31) =n/2{2a+(n-1)d}
  = 31/2{2×8+(31-1)4}
 =31/2{16+(30×4)
 =31/2(16+120)
 =31/2×126
 =31×63
Step-by-step explanation:
Similarly use 19 as (n) for the 19th term
