Hi,
Question shows this is a Arithmetic Sequences with "d"(the difference between the terms) being 3
*Note: Formulas for Arithmetic Sequences, in general, are as follows:
.
a%5Bn%5D=a%5B1%5D%2B%28n-1%29%2Ad
.
S%5Bn%5D=%28n%28a%5B1%5D%2Ba%5Bn%5D%29%29%2F2
If I am understanding Your Question, you are looking for the 30th term in this sequence
.
Using the Formula for the nth term
a%5Bn%5D=a%5B1%5D%2B%28n-1%29%2Ad
a%5B30%5D=a%5B1%5D%2B%2830-1%29%2A3
.
a%5B30%5D=+4+%2B%2829%29%2A3
a%5B30%5D=+highlight%2891%29
