Answer:576
Step-by-step explanation:
-8,0,8,...
Common difference=d=8-0
d=8
First term=a=-8
Using the formula
Tn=a + d x (n-1)
T74 = 74th term
T74=-8 + 8 x (74-1)
T74=-8 + 8 x 73
T74=-8 + 584
T74=576
The 74th term=576
To left of the decimal place it goes until the thousands place, to the right of the decimal it goes until the thounsadths place. HTH
