We can find a formula for nth term of the given sequence as follows:
1, 5, 12, 22, 35
The 1st differences between terms:
4, 7, 10, 13
The 2nd differences :
3, 3, 3
Since it takes two rounds of differences to arrive at a constant difference between terms, the nth term will be a 2nd degree polynomial of the form: 
, where c is a constant. The coefficients a, b, and the constant c can be found.
We can form the following 3 equations with 3 unknowns a, b, c:
Solving for a, b, c, we get:
a = 3/2, b = -1/2, c = 0
Therefore, the nth term of the given sequence is:
The little lines through the two sides of the triangle mean the sides are equal length.
Because the sides are equal, the two bottom angles are also the same.
Since angle B is given as 46 degrees, angle C is also 46 degrees.
The three inside angles of a triangle need to equal 180 degrees.
Angle A = 180 - 46 - 46 = 88 degrees.
The equation u can use is subtraction or division to get your answer if u use subtraction u will get an answer of 108 block of the town and if u use division u would get 28th block of the town
