2.5 km because 1.5 is half of 3 and half of 5 is 2.5
For this case we have the following sequence:
0.8
3.2
12.8
51.2
This sequence can be written as:
0.8 = 0.2 * 4 = 0.2 * 4 ^ 1
3.2 = 0.2 * 16 = 0.2 * 4 ^ 2
12.8 = 0.2 * 64 = 0.2 * 4 ^ 3
51.2 = 0.2 * 256 = 0.2 * 4 ^ 4
Therefore, we have that the generic expression for this case is:
an = 0.2 * 4 ^ n
Then, the next number is then:
a5 = 0.2 * 4 ^ 5 = 0.2 * 1024 = 204.8
answer
the next number in the pattern is 204.8
The two numbers are 48 and 18.
66 = l + s
l = 2 + 3s
66 = 2 + 3s + s
66 = 2 + 4s
66 - 2 = 64
64 = 4s
64 / 4 = 16
66 = l + 16
66 - 16 = 50
50 - 2 = 48
16 + 2 = 18
66 = 48 + 18
Step-by-step explanation:
If 200 g fertiliser required for 8 m^2 then for 1m^2 we'd need 25 g of fertiliser
(i) 14×25 = 350 g fertiliser would be needed for 14 m^2 land
(ii) 450÷25 = 18 m^2 land could be fertilised with 450 g fertiliser
