Answer:
The next step in the series is g 21 t.
Explanation:
Here, the given sequence is:
a3z, b6y , c9x, d12W,e15V and F18U
Here, the first term of each term is in the alphabetical sequence:
a, b, c, d, e and f.
So, here the first term of the next term is g.
Here, the second term of each term is in the multiple of 3:
3, 6, 9, 12, 15 and 18.
So, here the middle term of the next term is 21.
Similarly, the last term of each term is in the opposite alphabetical sequence:
z, y, x, w, v and u.
So, here the last term of the next term is t.
Now, combining all the terms of the next term we get:
The next term is g21t.
Hence, the next step in the series is g21t.
