Question

Найти a1,a2,a3, если an=2n-2

Answer 1

a1=2*1-2=2-2=0

a2=2*2-2=4-2=2

a3=2*3-2=6-2=4

Answer 2

To find the values of a1, a2, and a3, we need to substitute the values of n into the given formula for an = 2n - 2. Let's do that:

1. For n = 1: a1 = 2(1) - 2 a1 = 2 - 2 a1 = 0

2. For n = 2: a2 = 2(2) - 2 a2 = 4 - 2 a2 = 2

3. For n = 3: a3 = 2(3) - 2 a3 = 6 - 2 a3 = 4

So, the values of a1, a2, and a3 are: a1 = 0 a2 = 2 a3 = 4
