Answer:

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
