Answer:
The given sequence 6, 7, 13, 20, ... is a recursive sequence
Step-by-step explanation:
As the given sequence is

- It cannot be an arithmetic sequence as the common difference between two consecutive terms in not constant.
As
 ,
,  
As d is not same. Hence, it cannot be an arithmetic sequence.
- It also cannot be a geometrical sequence and exponential sequence. 
It cannot be geometric sequence as the common ratio between two consecutive terms in not constant.
As
 ,
,   
 
 ,
,  
As r is not same, Hence, it cannot be a geometric sequence or exponential sequence. As exponential sequence and geometric sequence are basically the same thing.
So, if we carefully observe, we can determine that:
- The given sequence 6, 7, 13, 20, ... is a recursive sequence. 
Please have a close look that each term is being created by adding the preceding two terms.
For example, the sequence is generated by starting from 1.
      
and 
      
for n > 1.

1. A = ¹/₂bh
    A = ¹/₂(25)(4)
    A = ¹/₂(100)
    A = 50 yd²
3. A = ¹/₂bh
    A = ¹/₂(3)(1)
    A = ¹/₂(3)
    A = 1¹/₂ cm²
