Question

write are arithmetic sequence with common difference 4 and find its 15th term?​

Answer 1

Hello !!

I will choose the arithmetic sequence bellow as example, see the same.

AP = 8, 12, 16, 20 ...

Now, I will find the 15th term of this sequence as ask the statement of the question.

An = Ak + (n - k) × d

A15 = 8 + (15 - 1) × 4

A15 = 8 + 14 × 4

A15 = 8 + 56

A15 = 64

Therefore, we have that the 15th term of this sequence that we created is 64.
