Question

find a formula for the general term of each of the following sequences - 4 - 1 2 5 8,​

Answer 1

Answer:

aₙ=-4+3(n-1)

Step-by-step explanation:

The first element is -4.

We notice that the sequence is with each step going up by 3.

This is a sequence of the type:

aₙ=a₁+d(n-1)

Whereas:

a₁ - is the first element

d - the 'step' of the sequence

n - the index of the elements (n=1 is the first, n=2 is the second, etc.)
