Question

what is the answer of
u1=4, Ur+1= 4, 3ur
​

Answer 1

Step-by-step explanation:

u = 4

ur = 3

find 3ur

then r = 3/4 = 0.75

therefore 4 × 3 × 3 / 4 = 3ur

4×4 gets cancelled remained 3 × 3 = 3² = 9

therefore 3ur = 9

or just basically

3 × 4 - 1 = 3 × 3 = 3² = 9

Answer 2

what is the answer of
u1=4, Ur+1= 4, 3ur


Answer : 9
