Question

What is the sixth term of a number pattern that begins with 185 and subtracts 15? A. 170 B. 95 C. 110 D. 125

Answer 1

So, the sixth term is 110

Explanation:

We are given patter has same common difference

because each subtracted by 15

so, this is arithematic sequence

and we have

`d=-15`

It begins with 185

so, first term is 185

`a_1=185`

now, we can use nth term formula

`a_n=a_1+(n-1)d`

For sixth term , n=6

so, we can plug values

`a_6=185+(6-1)* -15`

`a_6=110`
