<h3>What is the missing element in a sequence?</h3>
A sequence is a set of elements which observes at least a <em>defined</em> rule. In this question we see a sequence which follows this rule:
 (1)
      (1)
Now we prove that given expression contains the pattern:
n = 0 
7
n = 1
7 + (- 1)² · 2² = 7 + 4 = 11
n = 2
7 + (- 1)² · 2² + (- 1)³ · 3² = 11 - 9 = 2
n = 3
7 + (- 1)² · 2² + (- 1)³ · 3² + (- 1)⁴ · 4² = 2 + 16 = 18
n = 4
7 + (- 1)² · 2² + (- 1)³ · 3² + (- 1)⁴ · 4² + (- 1)⁵ · 5² = 18 - 25 = - 7

Answer:
1332 i think is how it will be writen
Step-by-step explanation:
 
        
                    
             
        
        
        
1. Can you describe what needs to be done here?
2. 5a-2<18
5a<20
a<4
3. 2a+8≥ -4(a+1)
2a + 8 ≥ -4a - 4
6a ≥ -12
a ≥ -2
 
        
             
        
        
        
Huh? What does that even mean lol
