Karim's dog weighs 1.5 pounds less than double the weight of Frank's dog. Karim's dog weighs 15 pounds. Which equation and solution can be used to find w, the weight of Frank's dog? Group of answer choices

15 = 2w + 1.5; w= 6.75

15 = 2w - 1.5; w = 8.25

w - 15 = 1.5; w = -13.5

w + 15 = 1.5; w= 16.5

Asequence has its first term equal to 4, and each term of the sequence is obtained by adding 2 to the previous term. if f(n) represents the nth term of the sequence, which of the following recursive functions best defines this sequence? (1 point) f(1) = 2 and f(n) = f(n − 1) + 4; n > 1 f(1) = 4 and f(n) = f(n − 1) + 2n; n > 1 f(1) = 2 and f(n) = f(n − 1) + 4n; n > 1 f(1) = 4 and f(n) = f(n − 1) + 2; n > 1 i will award !
