Answer:
Step-by-step explanation:
The question is not properly written.
Use the explicit formulas below to find a1 ,and a10 for each formula . Show your work a . An =n^3 +4 b . An =-5n+3
a) If An = n^3 + 4
To get a1, we will substitute n = 1 into the equation as shown;
a1 = 1^3 + 4
a1 = 1+4
a1 = 5
If An = -5n+3
A1 = -5(1)+3
A1 = -5+3
A1 = -2
b) If An = n^3 + 4
To get a10, we will substitute n = 10 into the equation as shown;
a10 = 10^3 + 4
a10 = 1000+4
a10 = 1004
If An = -5n+3
A10 = -5(10)+3
A10 = -50+3
A10 = -47
