A1=-15
a2=a1+d→-4=-15+d→d=11
Answer:-21
Step-by-step explanation:
23+22=45
45-24=21
then flip 24 and 45 to get negative

<h3>Properties of Logarithms</h3>
From the properties of logarithms, you can rewrite logarithmic expressions.
The main properties are:
- Product Rule for Logarithms -
- Quotient Rule for Logarithms -
- Power Rule for Logarithms -
The exercise asks the potential solutions for . In this expression you can apply the Product Rule for Logarithms.
Now you should solve the quadratic equation.
Δ=. Thus, x will be . Then:
The potential solutions are 2 and -8.
