a(n)=1+(n-1)(-5.7)

Answer 1

anybody

Answer 2

Shouldn't this be in the math section

Answer 3

Sequences are like normal functions (the only difference is that the domain, in case you already know what it is, are the positive integers).

So when you ask for the 1st, 4th and 10th elements, you only need to substitute these numbers into the equations, like this

A(1)= -3 + (n-1)(-2.2) = -3 + (1-1)(-2.2)= -3 + 0 = -1
A(4)= -3 + (n-1)(-2.2) = -3 + (4-1)(-2.2) =
A(10)= -3 + (n-1)(-2.2) = -3 + (10-1)(-2.2) =
