Answer:
The answer to your question is 3, 9, 19, 33, 51
Step-by-step explanation:
Sequence an = 2n² + 1
1st term a₁ = 2(1)² + 1 = 2(1) + 1 = 2 + 1 = 3
2nd term a₂ = 2(2)² + 1 = 2(2)² + 1 = 2(4) + 1 = 8 + 1 = 9
3rd term a₃ = 2(3)² + 1 = 2(3)² + 1 = 2(9) + 1 = 18 + 1 = 19
4rd term a₄ = 2(4)² + 1 = 2(4)² + 1 = 2(16) + 1 = 32 + 1 = 33
5th term a₅ = 2(5)² + 1 = 2(5)² + 1 = 2(25) + 1 = 50 + 1 = 51
Answer:
average = 52, 100 on fourth test
Step-by-step explanation:
average = 75 + 74 + 71 = 156 / 3 = 52
average = 52
b grade = 75 + 74 + 71 + 100 = 320 / 4 = 80
to get a b grade she must get 100 on her fourth test

Answer:
1, 3, 9, 27
Step-by-step explanation:
You need the first 4 terms, so let n = 1, and evaluate the expression. Then do the same for n = 2, n = 3, and finally n = 4.
n = 1
n = 2
n = 3
n = 4
