The first three terms of the sequence defined by the recursive formula are 2, -7/2 and -3/2
Given:
where,
n = number of terms
First term, a1 = 2
Second term, a2
a2 = {(2 - 1)/ 4} - 2
= 1/4 - 2
= (1-8) / 4
= - 7/4
Third term, a3
= {(3-1) / 4} - 2
= 2/4 - 2
= 1/2 - 2
= (1-4) / 2
= -3/2
Therefore, the first three terms of the sequence defined by the recursive formula are 2, -7/2 and -3/2

Answer:
114.3cm^3
Step-by-step explanation:
Square Pyramid Formulas derived in terms of side length a and height h: Volume of a square pyramid
V = (1/3)(Base area of a square)(Height of the square pyramid).
V = (1/3)areahight
Area of the square
A = 7 x 7
A = 49
V = (1/3)49 x 7
V = (1/3)343
V = 114.(a repeating term)3
since we rounded
V = 114.3cm^3
