Answer 1

The answer to this question is 4600

Answer 2

4600

Explanation:

There is a common difference d between consecutive terms in the sequence, that is

d = - 2 - (- 6) = 2 - (- 2) = 6 - 2 = 4

This indicates the sequence is arithmetic with sum to n terms

`S_(n)` =
`(n)/(2)` [ 2a₁ + (n - 1)d ]

where a₁ is the first term and d the common difference

Here a₁ = - 6 and d = 4 , thus

`S_(50)` =
`(50)/(2)` [ (2 × - 6) + (49 × 4) ]

= 25(- 12 + 196)

= 25 × 184

= 4600
