Question

Find the 15th term in the Arithmetic Sequence An = 3n-7 Question 1 options: a32 b 7 c 38 d -2 please help

Answer 1

A(15) = 3(15)-7 = 45-7 = 38.

SO, (C)38 IS THE ANSWER.

Answer 2

we have that

`An=3n-7`

to calculate the 15th term in the Arithmetic Sequence

substitute the value of n for n=15 in the formula above

`A(15)=3*15-7`

`A(15)=45-7`

`A(15)=38`

therefore

the answer is the option C

`38`
