This is a geometric sequence with first term a1 = -4 and common ratio r = 4
so nth term = a1* r^(n-1)
= -4 *4^(n-1)
Answer:
What type of math this is text me back!
Step-by-step explanation:
Here all three are the factor. {a+b} will be the sum and 1/2 is the term
Hopefully i am right
All the best !!
The easiest way to do it is graph it and count.
