Respuesta :
There is a pattern. Each number is added by 5. So take 22 and add 5 to get 27. Just repeat until you find your answer, which would be 42.
adds 5 each times
an=a1+d(n-1)
a1=first term
d=common difference
n=which term
first term is 2
common diffference is 5 (7-2=5)
so
an=2+5(n-1)
the nth term is 2+5(n-1) or 5n-3
an=a1+d(n-1)
a1=first term
d=common difference
n=which term
first term is 2
common diffference is 5 (7-2=5)
so
an=2+5(n-1)
the nth term is 2+5(n-1) or 5n-3
