In the sequence 3 8 13 18 what term of the series is the number 2218

By clearly looking at the sequence there are in Arithmetic Progression
So for finding which term is 2218 in that sequence
we have  x_{n} = a+ (n-1)d
Here,
a=3
 x_{n}=2218 & d=5(by looking at the sequence given)
by substituting those values we get our desired result
2218=3+(n-1)5
2218-3=(n-1)5
2215=(n-1)5
2215/5=n-1
453=n-1
n=454
so 454 term is 2218
