Answer:
3, 1, - 1, - 3 and - 15
Step-by-step explanation:
To find the first 4 terms substitute n = 1, 2, 3, 4 into the rule, that is
a₁ = 5 - 2(1) = 5 - 2 = 3
a₂ = 5 - 2(2) = 5 - 4 = 1
a₃ = 5 - 2(3) = 5 - 6 = - 1
a₄ = 5 - 2(4) = 5 - 8 = - 3
The first 4 terms are 3, 1, - 1, - 3
For 10th term substitute n = 10 into the rule
a₁₀ = 5 - 2(10) = 5 - 20 = - 15
