Question

The formula for deriving nth term of an arithmetic progression is ……….. [a+d, a+(n+1)d, a+(n-1)d]​

Answer 1

Answer:

n/2(2a+(n-1)d)

Step-by-step explanation:

n=no of terms

a=first term

d=difference

Answer 2

Answer:

formula is an = a1 + (n - 1 ) d

Step-by-step explanation:

This is the formula that will be used when we find the general (or nth) term of an arithmetic sequence. If you want derivation, I will answer later!
