Answer:
81
Step-by-step explanation:
the formula for an arithmetic sequence:
aₙ = a₁ + (n-1)d
where aₙ = the nth term
a₁ = the 1st term = -3
n = the term number = 13
d = the common difference = 7
Plugging in those values into the formula to find a₁₃:
a₁₃ = -3 + (13-1)7
= -3 + (12)7
= -3 + 84
= 81
The answer is 1.
Because if you simplify (divide) 19/19 you get one.
4/4 would also be 1. Any number divided to itself will always be 1.
Whereas 30/15 would be 2 because thirty divided by fifteen is 2
The answer is B(1,-2). This is the only point where the two lines intercept. & if you plug the numbers into the equations they fit.
