Arithmetic and Geometric Sequence Series Summation

This summation is the same as which series?

• 1 + 2 + 3 + 4 + 5 + 6

• (1 - 2) + (2 - 2) + (3 - 2) + (4 - 2) + (5 - 2) + (6 - 2)

• (1 - 2) + (6 - 2)

• (1 - 2) + (2 - 2) + (3 - 2) + (4 - 2)

The summation is the same as which series?

• (4+10) + (4+20) + (4+30) + (4+40) + (4+50) + (4+60) + (4+70) + (4+80) + (4+90) + (4+100) + (4+110)

• 1+2+3+4+5+6+7+8+9+10+11

• 4 + 110

• 4 + 10

Is this summation finite or infinite?

• Finite, because there are only 6 terms to add up.

• Infinite, because there are an infinite number of terms to add up.

Is this sum finite or infinite?

• Finite, because there are 4 terms to add up.

• Infinite, because there are an infinite amount of terms to add up (m goes from 1 to infinity).
