Answer:
Step-by-step explanation:
21,26
26 is the answer
15th term is 71
Explicit Rule for arithmetic sequence is: Tn = a + (n - 1)*(d), where a is the first term and d is the common difference
The first term is 1, hence a = 1
The common difference is 5 (6 - 1 = 5, 11 - 6 = 5...), hence d = 5
Tn = 1 + (n - 1)*(5)
We are trying to find the 15th number.
T₁₅ = 1 + (15 - 1)*(5)
= 1 + (14)*(5)
= 1 + 70
= 71

I will update this if I figure how it's solved as well.
Answer is in the picture bellow
O x = - 6 or x = 2
x² + 4x - 4 - 8 = 0
x² + 4x - 12 = 0
x² + 6x - 2x - 12 = 0
x(x + 6)x - 2(x + 6) = 0
(x + 6) (x - 2) = 0
x + 6 = 0 or x - 2 = 0
x = - 6 or x = 2
Thus, x = - 6 or x = 2
