Which of the following is moeilikely the next step in the series?

a3z, b6y. c9x, d12W. 615V. F18U

The next step in the series is g 21 t.

Step-by-step 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.
