You get answer C.
i thank it is B i hope that helped
3(5)+15= 30
because BIDMAS so we would multiply 3 by 5 then add the answer which would be 15 to 15 and we would get 30.
Step-by-step explanation:
let number be x
3(4+x)=2x
12 + 3x = 2x
12 = 2x - 3x
12 = -x
x= -12
Answer:
Step-by-step explanation:
It's an arithmetic sequence.
9 = 11 - 2
7 = 9 - 2
5 = 7 - 2
3 = 5 - 2
A) next three terms: 3 - 2 = 1, 1 - 2 = -1, -1 - 2 = -3
B) Common difference = -2
C) Recursive Function:
D) Explicit Function:
a₁ - first term
d - common difference
Substitute a₁ = 11 and d = -2:
