Question

-27/20+-9/10
Plz answer

/ is used to represent 'upon'​

Answer 1

Step-by-step explanation:

Think of the numbers before the equal signs as the numbers associated with terms in a series. Thus, term 2 1s 6, term 3 is 12, term 4 is 20, term 5 is 30, and term 6 is 42. Notice that the differences between successive terms is a sequence of steadily increasing even numbers, i.e. term 3 = term 2 + 6, term 4 = term 3 + 8, term 5 = term 4 + 10, term 6 = term 5 +12. If this is really the pattern producing these numbers, we can proceed as follows:

term 7 = term 6 + 14 = 42 + 14 = 56; term 8 = term 7 + 16 = 56 + 16 = 72, and to answer your question

term 9 + term 8 + 18 = 72 + 18 = 90, and you are correct.
