Answer:

3, 12, 48, 192

Step-by-step explanation:

To find the first 4 terms substitute n = 2, 3, 4 into the recursive formula, that is

a₂ = 4a₁ = 4 × 3 = 12

a₃ = 4a₂ = 4 × 12 = 48

a4 = 4a₃ = 4 × 48 = 192

Thus the first 4 terms of the sequence are 3, 12, 48, 192

Jarett's puppy weighed 3 3/4 ounces at birth at one week old, the puppy weighed 5 1/8 ounces at two weeks old the puppy weigh at

Mariulka [41]

Well, i find it helps to turn the fractions into decimals.
3 3/4 = 3.75
5 1/8 = 5.125

so now subtract:
5.125 - 3.75 = 1.375

so that means it weighs 1.375 ounces more each week

so then take the second week (5.125) and add on 1.375

5.125 + 1.375 = 6.5

now to convert that into a fraction (lowest terms) it would be:
6 1/5 ounces

Therefore,
Jarett's puppy will weigh 6 1/5 ounces at three weeks old.

Hope this helps and ave a great day! :D
