Answer:
Yow!
Step-by-step explanation:
a. common ratio = -2
b. an = a1 • r^n-1
a7 = 3 (-2^7-1)
= 3 (-2⁶)
= 3 (64)
a7 = 192
c. an = a1 • r^n-1
a11 = 3 (-2^11-1)
= 3 (-2¹⁰)
= 3 (1024)
a11 = 3072
d. 3072 - 192 = 2880
====================
a. comoon ratio = x³
b. an = a1 • r^n-1
a6 = x² (x³^6-1)
= x² (x³)⁵
= x² (x¹⁵)
a6 = x¹⁷
c. x¹⁷(x²) = x¹⁹
====================
a. common ratio = √3
b. an = a1 • r^n-1
a9 = 1 (√3^8-1)
= 1 (√3⁸)
= 1 (81)
a9 = 81
c. an = a1 • r^n-1
a12 = 1 (√3^12-1)
= 1 (√3¹¹)
= 1 (243√3)
a12 = 243√3

Answer:
1) common ratio: 2
an = a1 (r)^n-1
a7 = 3 (2)^7-1
a7 = 3 (2)^6
a7 = 3 (64)
a7 = 192
an = a1 (r)^n-1
a11 = 3 (2)^11-1
a11 = 3 (2)^10
a11 = 3 (1024)
a11 = 3072
3072 - 192 = 2880
