The general term is obtained by starting with the initial value 5 and then subtracting 4 each time you wish to generate a new term:
a2 = second term = 5+(2-1)(-4) = 5+(-4) = 1
General term:
an = nth term = 5+(n-1)(-4)
Thus, the 21st term is 5+(21-1)(-4) = 5 + (20)(-4) = -75 (answer)

Answer: 6 pigs and 3 chickens
Step-by-step explanation: you know that each pig has 4 legs and each chicken has 2 legs so start out by saying 9 pigs and 0 chickens which is 36 legs then try 8 pigs and 1 chickens and 8 times 4 = 32 + 2 which is 32 which is more than 30 then notice for every chicken there is you subtract 2 from 36
knowing this we can divide 6 by 2 and get 3 the number of chickens
so 6 pigs and 3 chickens
hope this helps mark me brainliest if it helped
False
lets say u have 2 sets of points (1,2) , (3,4)
now lets say (1,2) is (x1,y1) and (3,4) is (x2,y2)
slope = (y2 - y1) / (x2 - x1)
slope = (4-2) / (3-1) = 2/2 = 1
now, lets say (1,2) is (x2,y2) and (3,4) is (x1,y1)
slope = (y2 - y1) / (x2 - x1)
slope = (2 - 4) / (1 - 3) = -2/-2 = 1
in conclusion, the naming of the points will not effect the slope
