Question

Find the sum

69

Evaluate

n = 1 \sum 6 (3 n + 1)

Calculate

n = 1 \sum 6 3 n + n = 1 \sum 6 1

Calculate

More Steps

Evaluate

n = 1 \sum 6 3 n

Calculate

3 \times n = 1 \sum 6 n

Substitute 6 for n into formula i = 1 \sum n i = \frac{n ( n + 1 )}{2}

3 \times \frac{6 ( 6 + 1 )}{2}

Calculate

63

63 + n = 1 \sum 6 1

Calculate

More Steps

Evaluate

n = 1 \sum 6 1

Calculate

(6 - 1 + 1) \times 1

Calculate

6

63 + 6
