Question

example 5, 6, and 7). The sum of three consecutive integers is 417.
Let n be the first one. Write an equation that will determine
the three integers)

Answer 1

I = Prt
divide both sides by Pr
I /(Pr) = t

n + (n+1) + (n+2) = 417
3 n + 3 = 417
3 n = 414
n = 138
so
138 + 139 + 140
better be 417 :)
