30 just multiply 15 times 2 your welcome
The pattern is that every 2 numbers are a pair, the first being any selected number, and the second number next to is the number times 3.
3 x 3 = 9
4 x 3 =12
7 x 3 = 21
Therefor we type 16 x 3 = 48
48 is your next number.
Here, just substitute the value of n = 7
an = -6(n-1)
an = -6(7-1)
an = -6(6)
an = -36
In short, Your Final Answer would be -36
Hope this helps!
Answer:is there any picture?
Step-by-step explanation:
A system of linear equation consists of two or more linear equations with the two or more same variables. Such equations are called system of equations (or) simultaneous equations (or) a pair of equations.
Example:
x + y = 5 is one linear equation.
2x – y = 4 is another linear equation.
But x + y = 5, 2x – y = 4 together they form system of linear equation.
The solution to a system of linear equations in two variables is any ordered pair that satisfies each equation independently.
