STEP 1: Recall what is a sequence

STEP 2: Recall what is an arithmetic sequence

STEP 3: Recall what is a geometric sequence

STEP 4: Type in the missing number

The second number is got by multiplying the first one with 4 and so on. So, the last number in the sequence is got by multiplying 1024 with 4 to get 4096. This is a geometric sequence.
