In reference to patterns there is a process of getting from one term to another or to finding a certain term in the pattern. first two words ru

To establish a rule for a number pattern involving ordered pairs of x and y, we can find the difference between every two successive values of y. If the difference pattern is the same, then the coefficient of x in the algebraic rule (or formula) is the same as the difference pattern.

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
