Answer: 110 test were purchased
Step-by-step explanation:
Set P = number of packets of 10 test
Total cost = $30 + $11 x P = $151
$11xP = $151 - $30 = $121
P = $121/$11 = 11 packets were purchased
Test purchased = 11packets x 10 test/packet = 110 test were purchased

Answer:
- 3, 16, - 22, 54
Step-by-step explanation:
Using the recursive formula with a₁ = - 3, then
a₂ = - 2a₁ + 10 = - 2(- 3) + 10 = 6 + 10 = 16
a₃ = - 2a₂ + 10 = - 2(16) + 10 = - 32 + 10 = - 22
a₄ = - 2a₃ + 10 = - 2(- 22) + 10 = 44 + 10 = 54
Thus
the first 4 terms of the sequence are
- 3, 16, - 22, 54
