Set up an equation:
45 = 4x +5 Subtract 5 from both sides.
40 = 4x Divide by 10 on both sides
10 = x.

Answer:
= - 536
Step-by-step explanation:
The n th term of an arithmetic series is
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 10 and = - 144 , thus
10 + (n - 1)d = - 144 ( subtract 10 from both sides )
(n - 1)d = - 154
The sum to n terms of an arithmetic series is
= [ 2a₁ + (n - 1)d ] , thus
= [ (2 × 10) + (- 154) ]
= 4(20 - 154)
= 4 × - 134
= - 536
