n2(2a1+(n-1)d)
Sn=n2(a1+an)
an = a1 + (n – 1)d
2
What is An ARITHMETIC Sequence
when you subtract the number before in a sequence
adding the same number from one term to the next / can be -
when you divide the number before
3
What is the formula for depreciation
Vt = P(1 +r100)t
a2 + b2 = c2
Vt = P(1 -r100)n
Y = mx+b
