20. Write the first 4 terms of the sequence defined by the recursive
rule. (4.1 and 14.2))
a. f(1) = 3, f(n) = f(n-1) + 4, n > 1
b. f(1) = -2, f(n) = f(n-1) -3,n> 1
c. f(1) = 3, f(n)= f(n-1).-2,n22
d. f(1) = -2, f(n)= f(n-1) -4,0 2 2

828. all there is to it!

here, if you ever need with rounding (or other forms of arithmetic/math) again, use this:

thats the rounding one, but if you just click the top left, it shows you all the calculators you may need!

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
