Avery and Collin were trying to challenge each other with equations for sequences. Avery was looking at an explicit equation that Collin wrote.



t(n) = 4. 5n − 8



Write the first 4 terms for the sequence.



What would Avery do to write the 15th term of this sequence?



Write a recursive equation for this sequence

Respuesta :

The first four terms of the arithmetic sequence will be -12, 8, 28 and 48.

How to calculate the sequence?

From the information given, the equation is written as:

t(n) = 4. 5n − 8

First term = 4 × [5(1) - 8)]

= 4 × -3

= -12

Second term = 4. 5n − 8

= 4 × 5(2) - 8

= 4 × 2

= 8

Third term = 4. 5n − 8

= 4 × 5(3) - 8

= 4 × 7

= 28

Fourth term = 4 × 5(4) - 8.

= 4 × (20 - 8)

= 4 × 12

= 48
