To find the 7th value in the arithmetic sequence described by the explicit formula An=2.5+(n−1)4, we substitute n=7 into the formula.
A7 = 2.5 + (7-1)4
= 2.5 + 6*4
= 2.5 + 24
= 26.5
Therefore, the 7th value in the arithmetic sequence is 26.5.
A7 = 2.5 + (7-1)4
= 2.5 + 6*4
= 2.5 + 24
= 26.5
Therefore, the 7th value in the arithmetic sequence is 26.5.
