Step-by-step explanation:
number of plants = 647
number of plants in 1 rows = 20
number of rows =
647 ÷ 20 = 32 and remainder = 7 =>
647 = 32 × 20 + 7 =>
647/20 =
(32 × 20 + 7) / 20 =
32 + 7/20 =
32 7/20
17,19,23 are the prime numbers
Answer:
Step-by-step explanation:
Since the sequence is geometric (it multiplies the previous number each time). The nth term sequence would be
Because the sequence multiplies by 3 each time, The base number in that equation would be .
So of the equation would be:
.
Compare the 2 equations:
4, 12, 36
3, 9 ,27
The difference between the 2 equations is: 1, 3, 9 which itself is a geometric sequence so the nth term of this new equation is: .
Combine these 2 equations together and you get:
.
