To find the 70th term of the arithmetic sequence, we can use the formula for the nth term of an arithmetic sequence:
nth term = first term + (n-1) * common difference
In this sequence, the first term (a) is 3 and the common difference (d) is 9 (since each term is 9 greater than the previous term).
Using the formula, we substitute these values in to find the 70th term:
70th term = 3 + (70-1) * 9
= 3 + 69 * 9
= 3 + 621
= 624
Therefore, the 70th term of the arithmetic sequence is 624.
find the 70th term of the following of the following arithmetic sequence.
3,12,21,30,...
