Answer:
36
Solution:
Find the value of k
a2 - a1 = a3 - a2
(4k) - (2k-2) = (7k-7) - (4k) k= 9
4k-2k + 2 = 7k-7 - 4k
2k + 2 = 7k-7 - 4k
2k + 2 = 3k-7
2k - 3k + 2 = -7
2k - 3k = -7 - 2
-k = -9
-k/-1 = -9/-1
k = 9
Substitution for the second term
a2 = 4k
= 4(9)
a2 = 36
36 is the value of the second term
