Find the value of two numbers of their sum is 144 and their difference is 22

83 + 61 = 144

83 - 61 = 22

Step-by-step explanation:

x + y = 144

x - y = 22

2x = 166

x = 83

83 + y = 144

y = 144 - 83

y = 61

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
