Answer:
Point C
Step-by-step explanation:
Answer:
The number is 19
Step-by-step explanation:
7 less than a number = x - 7
2x - x - 7 = 12
Subtract x from 2x
x - 7 = 12
Add 7 to both sides of the equation
x = 19
The number is 19
Hope this helps :)
= 9n + 63
generate the first few terms using the recursive equation
f(1) = 72
f(2) = 72 + 9 = 81
f(3) = 81 + 9 = 90
f(4) = 90 + 9 = 99
the sequence is 72, 81, 90, 99, .....
This is an arithmetic sequence whose n th term formula is
= + (n - 1 )d
where is the first term and d the common difference
d = 99 - 90 = 90 - 81 = 81 - 72 = 9 and = 72
= 72 + 9(n - 1) = 72 + 9n - 9 = 9n + 63 ← explicit formula
