Answer 2

Given:–

• Arithmetic progression

Here,

1. First term (a) = 8
2. Common difference (d) = preceding term - initial term = 4-8 = -4
3. Number of terms = 10

To find:–

➳ Sum of ten terms

Formula to be used:–

➨ Sum of n terms is given by

n/2 (2a+ (n-1)d)

Calculation :–

Sum will be

n/2 (2a+ (n-1)d)

⟹10/2 ( 2× 8 + (10-1)(-4)

⟹5 ( 16 + (9)(-4)

⟹5(16-36)

⟹5× -10

⟹-50

Answer

-50
