Dante is making a necklace with 18 rows of tiny beads in which the number of beads per row is given by the series 3 + 10 + 17 + 24 +

if you were to write this series in summation notation, give

the lower limit of the sum

the upper limit of the sum

the explicit formula of the sum

Lower limit of the sum: 0

Upper limit of the sum: 17

Explicit formula: ∑(3+7i)

Step-by-step explanation:

Noting that each row has 7 more beads than the previous one and that the series also begins with 3, the formula is:

∑(3+7i)

The lower limit is 0, since 3+ (7 * 0) = 3

When i = 0 you get the value of beads from the first row, when i = 1 you get the value of beads from the second row and so on. Given this, the upper limit is 17.
