Four-fifths of a number exceeds two-thirds of the number by 10 what is the number

Four-fifths of a number exceeds two-thirds of the number by 10. The number is 75

Solution:

Let the number be "x"

Given that,

Four-fifths of a number exceeds two-thirds of the number by 10

Here, "exceed" means that more than or addition

Therefore, we can say,

Four-fifths of a number = two-thirds of the number + 10

Writing it mathematically we get,

Thus the number is 75

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
