Need help with this ASAP
Mariana [72]

Answer:

Sequence: 13, 20, 27

Rule: Tn = 7n + 6

Step-by-step explanation:

The 3 other numbers that can form an arithmetic progression is 13, 20, 27...

The nth term of an arithmetic progression is expressed as;

Tn = a + (n-1)d

a is the first term = 13

n is the number of terms

d is the common difference = 20 - 13 = 27 - 20

d = 7

Substitute

Tn = 13 + (n-1)(7)

Tn = 13 + 7n - 7

Tn = 7n+13-7

Tn = 7n + 6

This gives the required rule

If f(x)=x^2+7, what is the equation for f^-1(x)???
Marrrta [24]
Given: f(x) = x² + 7

Let  y = x² + 7
x = y² + 7 (since the inverse is reflected about the y = x line, the coordinates are interchangeable)

y² = x - 7
y = √(x - 7)

Thus, the inverse function f^(-1)x = √(x - 7)
