Find the first four (4) terms of the sequence if an=(4) an-1 and a1 =3

3, 12, 48, 192

Step-by-step explanation:

To find the first 4 terms substitute n = 2, 3, 4 into the recursive formula, that is

a₂ = 4a₁ = 4 × 3 = 12

a₃ = 4a₂ = 4 × 12 = 48

a4 = 4a₃ = 4 × 48 = 192

Thus the first 4 terms of the sequence are 3, 12, 48, 192

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
