Answer:
Step-by-step explanation:
We are given;
A geometric sequence;
-2,10,-50
Required to determine the nth term
The nth term in a geometric sequence is given by the formula;
where is the first term and r is the common ratio;
In this case;
r = 10 ÷ -2
= -5
Therefore;
To get the nth term in the given geometric sequence we use;
Thus, the nth term is

Answer:
156,23
Step-by-step explanation:
let the numbers be x and y and x>y
x+y=179
x-y=133
add
2x=312
x=156
156+y=179
y=179-156=23
The answer would be 120 hope this helps!!
