Solution:

Given series is:

7 , 4 , 5 , 12 , ? , 424

We have to find the missing term

Let us analyse the logic used in the series

$First\ term = 7\\\\Second\ term = 7 \times 0.5 + 0.5 = 3.5 + 0.5 = 4\\\\Third\ term = 4 \times 1 + 1 = 4 + 1 = 5\\\\Fourth\ term = 5 \times 2 + 2 = 10+2 = 12\\\\Fifth\ term = 12 \times 4 + 4 = 48+4= 52\\\\Sixth\ term = 52 \times 8 + 8 = 416+8=424$

Complete series is:

7 , 4 , 5 , 12 , 52 , 424
