(First difference is constant)

Answer 4

an + b = a↓n

Question 5

General form
(When first difference is NOT constant)

Answer 5

an² + bn + c = a↓n

Question 6

seconds only

Answer 7

Carl Friedrich Gauss

Question 8

formation of arithmetic series formula

Answer 8

denote the sum of the first n terms of
an arithmetic sequence

rewrite the sum in reverse order

Form equation 1 and 2

Add equation 1 and 2

combine like terms (a₁ + aₙ)

Question 9

arithmetic series formulas:

Answer 9

Sn=(a₁ + aₙ)n/2

Sn=(a₁ + aₙ)/2

Sn=n[2a₁ + (n-1)d]/2
