Find the 12th term in the arithmetic sequence an = 3 − 6(n − 1)
2 answers:
Answer: -63
Step-by-Step Solution:
=> an = 3 - 6(n - 1)
Hence,
=> a = 3
=> d = -6
=> n = 12
Therefore,
an = 3 - 6(n - 1)
a12 = 3 - 6(12 - 1)
a12 = 3 - 6(11)
a12 = 3 - 66
=> a12 = -63
12th Term of this A.P is -63
Answer:
-63
Step-by-step explanation:
3 - 6(12 - 1) = 3 - 6(11) = 3 - 66 = -63

Step-by-step explanation:
x = -10, y = 10
y= -4x+4
m1×m2 = -1
-4 × m2 = -1
m2 = 1/4
y-y1 = m(x-x1)
y-10 = 1/4(x+10)
y-10 = 1/4x +10/4
(×4)
4y-40=x+10
4y=x+50
x-4y+50=0
