Find the 11th term of the arithmetic sequence -5x - 1, 8x + 4, -112 + 9, ... help

Bingel [31]

here's the solution,

first term (a) = -5x

common difference (d) = (8x + 4) - (-5x - 1)

= 13x + 5

now, we know,

=》

$nth \: term = a + (n - 1) \times d$

=》

$11th \: \: term = - 5x + (11 - 1) \times (13x + 5)$

=》

$11th \: \: term = - 5x + 130x + 50$

=》

$11th \: \: term = 125x + 50$
