Answer:
8
Step-by-step explanation:
The answer would be 8 because the question would be
24 ÷ x + 5 × 3 + 2=20 right?
The first thing you would want to do is multiply the 5 and the 3 because of PEMDAS which should give you 24 ÷ x + 15 + 2 = 20.
15 plus 2 is 17 and then you would subtract 17 from 20 which would give you 3. So you know know that 24÷x has to be 3 and 24÷3 is 8 so x=8.
Hope this helped!
Step 3 is wrong.
It should be 4/7 / 5/8
4/7 x 8/5
32/ 35
Answer:
Step-by-step explanation:
Step-by-step explanation:
in a geometric sequence there is a constant factor x that is multiplied with every previous term to create the next one.
a2 = 20
a5 = 1280 = a2×x×x×x = a2×x³ = 20x³
64 = x³
x = 4
=> a1 = 5
therefore
an = an-1×4 =
n > 1
