Question

What is the 15th term of the sequence 4-5n

plss answer this​

Answer 1

-71

Explanation:

We are given the general term of sequence:

`\displaystyle \large{a_n = 4 - 5n}`

This makes our job easier since the question gives a general term instead of sequence itself.

We want to find the 15th term — substitute n = 15.

`\displaystyle \large{a_(15) = 4 - 5(15)} \\ \displaystyle \large{a_(15) = 4 - 75} \\ \displaystyle \large{a_(15) = - 71}`

Therefore, the 15th term is -71
