Answer:
Step-by-step explanation:
a₁ = 1 - 5(1 - 1) = 1 - 5·0 = 1
a₂ = 1 - 5(2 - 1) = 1 - 5·1 = 1 - 5 = a₁ - 5
a₃ = 1 - 5(3 - 1) = 1 - 5·2 = 1 - 5 - 5 = a₂ - 5
a₄ = 1 - 5(4 - 1) = 1 - 5·3 = 1 - 5 - 5 - 5 = a₃ - 5
and so on, therefore:
<h3> aₙ = aₙ₋₁ - 5</h3>Answer:
243 ways
Step-by-step explanation:
Calculating the number of posible outcomes:
We have n trials.
Each trial has m possible outcomes.
The total number of outcomes is:
In this question:
5 questions, that is, 5 trials, so
Each question has 3 options(True, false or unanswered). So
How many ways?
