***
First reason:

In this series, 5 is added to the previous number; the number 70 is inserted as every third number.

Second reason:

Number 70 is used in this series as every third number.  

you will carry on this series by adding 5 in previous number

Explanation

There are two series:

First                                  Second  

6+4=10                            8+3=11

10+4=14                        11+4=15

14+4=18                        15+5=20

Explanation

3, 3, 5, 5, 7, 7, 9,9

Explanation

• Q U Q!= R
• ***
• Q=rational no. s
• 
  
• Q! = everything except it in the set here we take it as irrational no. s
• 
  
• rational no. s + irrational no. s = real no. s
• so the answer is R
• ***
additional information: ?

• 
  The letters R, Q, N, and Z refer to a set of numbers such that:
• 
  
• R = real numbers include all real numbers [-inf, inf]
• 
  
• Q= rational numbers ( numbers written as ratio)
• 
  
• N = Natural numbers (all positive integers starting from 1. (1,2,3....inf)
• 
  
• z = integers ( all integers positive and negative ( -inf, ..., -2,-1,0,1,2....inf)

Explanation

1 -1 -2 -3 -5 -8 -13----------? 

Added the previous amount so -8+ (-13) is equal to -21

Explanation

Step-by-step explanation:

Now the next even number is 2.

Similarly,

Therefore, the next number should be:

Hence, the next number of the sequence is 86.
