To solve this problem you must apply the proccedure shown below:
1. You have the following sequence of numbers given in the problem above:
[tex] 4, 8, 12, 20, , 52 [/tex]
2. As you can see, the third term is the sum of the first term and the second term, then, the missing one , which is the fifth term, must be the sum of the third term and the fourth term:
[tex] 12+20=32 [/tex]
3. Therefore, when you sum the fourth and the fith term, you obtain the last one:
[tex] 20+32=52 [/tex]
The answer is: [tex] 32 [/tex]
