Answer:
(a-c)/b = x
Step-by-step explanation:
a = bx + c
subtract 'c' from each side to get:
(a-c) = bx
divide each side by 'b' to get:
(a-c)/b = x
Formula of the sum of the 1st nth term in a Geometric Progression:
Sum = a₁(1-rⁿ)/(1-r), where a₁ = 1st term, r = common ratio and n= rank nth of term (r≠1)
Sum = (-11)[1-(-5⁸)] /[(1-(-5)]
Sum = (-11)(1- 390625)/(6)
SUM = 716,144
Multiply 14 to each term: 14a+70+84b
