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

42 square ft because 4 times 3 is 12 and 10 times 3 is 30. 30+12=42
(7 cm)*(10 cm) = 70 cm^2
The area is the product of length and width.
3 hundreds + 7 hundreds = 1 thousand
300 + 700 = 1000
Answer:
x = 2
Step-by-step explanation:
(16 = 
and 8 = 
)
Since the base number is 2, the exponents must equal each other.
So:
12x = 3x+18
9x = 18
x = 2
