᪥ The formula to find the 31st term is : ![\sf \: a_{n} = a_{1} + (n - 1) \times d](https://tex.z-dn.net/?f=%20%5Csf%20%5C%3A%20a_%7Bn%7D%20%3D%20%20a_%7B1%7D%20%2B%20%28n%20-%201%29%20%5Ctimes%20d)
᪥ In the formula,
represents the first term of the sequence.
᪥
is the number of terms, In our case n is 31.
᪥
is the common difference between the terms, In our case d is 4.

Answer:
0.075 sq km
Step-by-step explanation:
Given that there is a rectangular field with dimensions of length =300 m and width = 250 m.
We have to calculate area of this rectangle in the units of square kilometres.
Let us convert length and width into km
1000m = 1 km
Hence length = 300/1000= 0.3 km and
width = 250/1000 = 0.25 km.
ARea = length x width = 0.3 x 0.25
=0.075 square km.
Answer:
Quotient = division of one number by another
![\implies \textsf{quotient of 30 and 6} = \sf \dfrac{30}{6}](https://tex.z-dn.net/?f=%5Cimplies%20%5Ctextsf%7Bquotient%20of%2030%20and%206%7D%20%3D%20%5Csf%20%5Cdfrac%7B30%7D%7B6%7D)
![\implies \textsf{3 subtracted from } \sf \dfrac{30}{6}=\dfrac{30}{6}-3](https://tex.z-dn.net/?f=%5Cimplies%20%5Ctextsf%7B3%20subtracted%20from%20%7D%20%5Csf%20%5Cdfrac%7B30%7D%7B6%7D%3D%5Cdfrac%7B30%7D%7B6%7D-3)
The quotient of 30 and 6 can also be written as the ratio 30 : 6
Therefore, the solution is (30:6) - 3
