Math = 3x + 1
Spelling = x + 8
Math - Spelling = 3x + 1 - x - 8
Math - spelling = 2x - 7
If x = 8
The 2*8 - 7 = 16 -7 = 9 <<<<< answer

Answer:
<u>The next two terms for the geometric sequence are - 108 and - 324.</u>
Step-by-step explanation:
1. Let's find the next two terms for the geometric sequence which first three terms are as follows:
- 4, 12, - 36.....
Aₓ = Aₓ₋₁ * 3 ; A₁ = - 4
A₁ = - 4
A₂ = A₁ * 3 = - 4 * 3 = - 12
A₃ = A₂ * 3 = - 12 * 3 = - 36
A₄ = A₃ * 3 = - 36 * 3 = - 108
A₅ = A₄ * 3 = - 108 * 3 = - 324
<u>The next two terms for the geometric sequence are - 108 and - 324.</u>
