Answer:

a_{n+1} = a_{n} + 3 ; a₁ = 1

Step-by-step explanation:

Given

1, 4, 7, 10, 13, 16, ......

Note the difference in consecutive terms is constant, that is

4 - 1 = 7 - 4 = 10 - 7 = 13 - 10 = 16 - 13 = 3

Thus to obtain the next term in the sequence ( recursive formula )

Add 3 to the previous term

a_{n+1} = a_{n} + 3 ( with a₁ = 1 )

Ksivusya [100]

Answer:

1.96 smaller pizzas can fit into the larger pizza.

Step-by-step explanation:

Area of smaller pizza:

π × (10/2)^2 = π × 5^2 = 25π square inches

Area of larger pizza:

π × (14/2)^2 = π × 7^2 = 49π square inches

Ratio of area of larger pizza to area of smaller pizza: 49π / 25π = 1.96
