Help please thank you

Answer 1

Answer:

arithmetic series

Step-by-step explanation:

We are adding 1 each time , so this is an arithmetic sequence

a1 =5

The common difference is 1  so d=1

an = a1+d(n-1)

an = 5 + 1(n-1)

an = 5+n-1

an = n+4

If we have an arithmetic sequence, we have an arithmetic series when we add the arithmetic sequence
