Can you solve it on a pice of paper and send the picture. Please I need to know how to do it step by step

Answer 1

f₁₂ = -26

Explanation:

The general term of an arithmetic sequence is

`f_n=f_1+(n-1)d`

For your given values of f₁ and d, and for n=12, the term is

... f₁₂ = 150 + (12-1)·(-16) = 150 -176

... f₁₂ = -26
