Plss answer the above question with setp by step solution
​

Answer 1

Answer:

» 49^(n -1) + 6 = 7^(2n - 1)

» 7^(2n - 1)/7 + 6 = 7^(2n - 1)

Substitute 7^(2n - 1) = a

» a/7 + 6 = a

» a + 42 = 7a

» 6a = 42

» a = 7

Therefore, 7^(2n - 1) = 7

» 2n - 1 = 1

» n = 1

Therefore, the value of n is 1.
