Question

find the 100th and nth term for -1, -2, and -3 (ALGEBRA) pls I will give brainliest

Answer 1

Answer:

$a=-1\\d=-2-(-1)=-1$

To find nth term :

$\implies$ $a_{n}=a+(n-1)d$

To find 100th term : n=100

$\implies$ $a_{100}=-1+(100-1)(-1)$

$\implies$ $a_{100}=-1+(99)(-1)$

$\implies$ $a_{100}=-1-99$

$\implies$ $\boxed{a_{100}=-100}$
