a1 = 1, a2 = 3

a2 = a1 + (2 - 1)d = a1 + d

d = a2 - a1 = 3 - 1 = 2

sn = (a1 + an) × n/2

s60 = (a1 + a60) × 60/2

a60 = a1 + 59d = 1 + 118 = 119

s60 = (1 + 119) × 60/2 = 120 × 60/2 = 3600

36a^2/42ac - 36a^2 + 49c^2/42ac + 49c^2 - 252ac/42ac = 36a^2 - 36a^2 - 49c^2 + 49c^2 - 252ac/42ac = -252ac/42ac = - 252/42 = -6
