An arithmetic sequence is a sequence where each term after the first is obtained by adding a constant difference to the preceding term.
The constant difference between consecutive terms. Can be positive, negative, or zero.
an = aā + (n-1)d, where aā is the first term, d is the common difference, and n is the term number.
Sn = n/2(aā + an) or Sn = n/2[2aā + (n-1)d], where n is the number of terms.
First term: 2, Common difference: 3
10th term: aāā = 2 + (10-1)Ć3 = 29
Sāā = 10/2(2 + 29) = 5 Ć 31 = 155
Given terms: 7, 12, 17, 22 ā d = 5
An arithmetic sequence is a sequence of numbers where the difference between consecutive terms is constant. This constant difference is called the common difference.
Use the formula: an = aā + (n-1)d, where aā is the first term, d is the common difference, and n is the term number.
Use the formula: Sn = n/2(aā + an) or Sn = n/2[2aā + (n-1)d], where n is the number of terms.
