Answer:
24 and 144
Step-by-step explanation:
a = 4
t4 = 864
864 = 4*r^(4 - 1) divide by 4
216 = r^3 Take the cube root of 216
6 = r
Note you can find the cube root of any number by using your calculator.
- 216
- y^x or x^y or ^
- 0.333333333333
- =
- 5.99999999 which rounded is 6
t2 = a * r^(2 - 1)
t2 = 4 * 6^1
t2 = 24
=================
t3 = a*r^(3 -1)
t3 = 4 * 6^2
t3 = 4 * 36
t3 = 144
