Kevin started the number pattern shown below using the rule "start with 1, multiply the previous number by 3 then add 2 to the result to get the next number." 1, 5, 17, …… What is the fifth number in her pattern?

Respuesta :

Answer: 161

Step-by-step explanation:

From the question, the rule is that we start with 1, multiply the previous number by 3 then add 2 to the result to get the next number.

Based on the numbers already given such as 1, 5, 17, the 4th number will be:

= (17 × 3) + 2

= 51 + 2

= 53

The 5th number will be:

= (53 × 3) + 2

= 159 + 2

= 161
