Question

A1=-9 an+1=an+4 первых 6 членов пж!!!!!!!!!

Answer 1

D = An+1-An=4
Первый член = -9
Второй = -5
Третий = -1
Четвёртый = 3
Пятый = 7
Шестой = 11

Answer 2

Sure, I'll help you find the first six terms of the sequence defined by the recurrence relation:

A(n+1) = A(n) + 4 with the initial condition: A(1) = -9

To find the first six terms, we start with the given initial condition and apply the recurrence relation successively:

1. A(1) = -9 (given)
2. A(2) = A(1) + 4 = -9 + 4 = -5
3. A(3) = A(2) + 4 = -5 + 4 = -1
4. A(4) = A(3) + 4 = -1 + 4 = 3
5. A(5) = A(4) + 4 = 3 + 4 = 7
6. A(6) = A(5) + 4 = 7 + 4 = 11

So, the first six terms of the sequence are: -9, -5, -1, 3, 7, 11
