Question

Find the 12th term in the arithmetic sequence an = 3 − 6(n − 1)

Answer 1

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 2

-63

Explanation:

3 - 6(12 - 1) = 3 - 6(11) = 3 - 66 = -63
