gabrielle's age - 48
gabrielle's age is three times mikhail's age.
g = 3m
the sum of their ages is 64.
g + m = 64 :
replace g with 3m
3m + m = 64
4m = 64
m = 16 :
what is gabrielle's age?
g = 3(16)
g = 48
164 and 287
their difference is 7-4 = 3 ratio units, so each ratio unit must stand for 123/3 = 41.
then the numbers are 4·41 and 7·41, or 164 and 287.
given that in a sequence general term i.e. nth term is given by
to find out the first term and pattern of term and compare with those given
to find first term put n=1
let us find
hence both the statements are the same.
or both sequences meant by two different conditions are one and the same
