Whats the answer to (5² -4) ∙ 2 – 18

Solving the equation we get 24

Step-by-step explanation:

We need to solve the equation

We will solve using DMAS rule i.e first bracket will be solved, then multiplication and at the end subtraction will be done.

First we will solve the bracket

Now multiply 21 by 2

Now subtract

So, solving the equation we get 24

answer:

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
