Final answer:
The sum of the arithmetic sequence from 1 to 102 is 5253.
Step-by-step explanation:
The given question asks for the sum of an arithmetic sequence from 1 to 102, with a common difference of 1. We can use the formula for the sum of an arithmetic series to find the answer.
The formula is S = (n/2)(a + l), where S is the sum, n is the number of terms, a is the first term, and l is the last term. In this case, n = 102, a = 1, and l = 102.
Plugging in these values into the formula, we get S = (102/2)(1 + 102) = 51(103) = 5253.
