Find a formula for the nth term in this arithmetic sequence:
Sati [7]

The nth term of the arithmetic sequence is Tn = -7 + ( n - 1) 6

<h3>What is an arithmetic sequence?</h3>

An arithmetic sequence is defined as a sequence of numbers where the differences between every two consecutive terms is the same  through out the sequence.

The nth term of an arithmetic sequence is expressed as;

an = a + ( n - 1) d

Where;

  • a is the first term
  • n is the number of terms
  • d is the common difference

Substitute the values

an = -7 + ( n - 1) 6

Thus, the nth term of the arithmetic sequence is Tn = -7 + ( n - 1) 6
