Question

The rule to get from one term to the next in a

sequence is
Xn+1 = 2xn - 3
Calculate the value of x3 if
a) x₁ = 7
b) x₁ = 9

Answer 1

Explanation:

When x_1 =7 then you can figure out by given condition say X_n+1= 2X_n-3

then X_2= 11 by substituting the value of X_1 as 7 similarly you can find out the value of X_3 by substituting X_2 as 11 so X_3 =19.

Similarly you can find out b)
