♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

5 {x}^{2}  - 5x + 1 = 0

(x -  \frac{5 +  \sqrt{5} }{10} )(x -  \frac{5 -  \sqrt{5} }{10} ) = 0 \\

Thus :

x =  \frac{5 + \sqrt{5} }{10}  \\

x =  \frac{5 -  \sqrt{5} }{10}  \\

Can someone please help
Sloan [31]

Answer:

41

Step-by-step explanation:

an = a1 + (n-1)d

a_n = the nᵗʰ term in the sequence = 10

a_1 = the first term in the sequence = 5

d = the common difference between terms = 4

a10 = 5 + (10-1)4

a10 = 5 + (9)4

a10 = 5 + 36

a10 = 41
