Answer 1

46

Explanation:

You need to replace i with 2,3,4,5.

i=2, 6+1

3, 9+1

4, 12+1

5, 15+1

sum=46

Answer 2

Answer: B) 46

Explanation:

The summation of 3i + 1 from i = 2 to i = 5 can be calculated by finding the value of each term and then adding them up ... or.... using the formula:

i = 2: 3(2) + 1 = 7

i = 3: 3(3) + 1 = 10

i = 4: 3(4) + 1 = 13

i = 5: 3(5) + 1 = 16

TOTAL = 46

`\text{Equation: }(a_1+a_5)/(2)* n\\\\.\qquad =(7+16)/(2)* 4\\\\.\qquad =23* 2\\\\.\qquad =46`
