Here is how the Sum of Last N Terms of Arithmetic Progression equation looks like.

174 = (\frac{6}{2}) \cdot ((2 \cdot 3) + (4 \cdot ((2 \cdot 10) - 6 - 1)))

174 = (\frac{6}{2}) \cdot ((2 \cdot 3) + (4 \cdot ((2 \cdot 10) - 6 - 1)))

174 = (\frac{6}{2}) \cdot ((2 \cdot 3) + (4 \cdot ((2 \cdot 10) - 6 - 1)))

Sum of Last N Terms of Arithmetic Progression Solution

Follow our step by step solution on how to calculate Sum of Last N Terms of Arithmetic Progression?

FIRST Step Consider the formula

S n(End) = (\frac{n}{2}) \cdot ((2 \cdot a) + (d \cdot ((2 \cdot n Total) - n - 1)))

Next Step Substitute values of Variables

∴

S n(End) = (\frac{6}{2}) \cdot ((2 \cdot 3) + (4 \cdot ((2 \cdot 10) - 6 - 1)))

Next Step Prepare to Evaluate

∴

S n(End) = (\frac{6}{2}) \cdot ((2 \cdot 3) + (4 \cdot ((2 \cdot 10) - 6 - 1)))

LAST Step Evaluate

∴

S n(End) = 174
