Answer: F. Students 1 and 4.
Step-by-step explanation: Students 1 and 4 because algebraic expressions do not have equal signs, and students 1 and 4 don't have equal signs, as equal signs can be found in algebraic <u>equations</u>.
The explicit rule for any arithmetic sequence is:
a(n)=a+d(n-1), a=initial term, d=common difference, n=term number
In this case a=-3 and d=7 so:
a(n)=-3+7(n-1)
a(n)=-3+7n-7
a(n)=7n-10
KX = x+4 so solve for k.
Divide both sides of the equation by x and you get K=4.
Plug it in, and you get (4)(7)=28
Your answer is 28.
