Answer:
aₙ = a₁ + (n-1).d
103
107
Step-by-step explanation:
This is an arithmetic sequence because the difference (d) between 2 successive numbers is constant.
d = 91 - 87 = 95 - 91 = 99 - 95 = 4
If the first term is a₁, we can find the n term using the following expression.
Here, we want to find the fifth and sixth elements.
a₅ = 87 + (5-1).4 = 103
a₆ = 87 + (6-1).4 = 107
1. a² - ( b ² - 2bc + c² ) = a ² - b ² + 2bc - c²
2. 8p² - 18 q²
3. 3ab² - c²d + 3ab - b²c²
4. x² - 2x + 1
I think the answer is (origin)
