Consider the sequence of numbers 50, 48, 46, 44, using n to represent a position of a number in this sequence, write an expression that allows you to calculate the nth number

The given sequence is

Here the first term, a is 50.

And the difference between two consecutive terms are

So the difference is constant, which is -2. Therefore the sequence is arithmetic .

And the nth term of aritmnetic series is given by

Substituting the values of a and d, we will get

true

step-by-step explanation:

(-1,-0.5)
