Question

The sum of the four consecutive terms is 20 and sum of first and third is 8 find the term​

Answer 1

Step-by-step explanation:

let x be the number.

(x + 1) + (x + 2) + (x + 3) + (x + 4) = 20

4x + 10 = 20

4x = 10

x = 10/4

x = 5/2

Sum of first and third is 8,

(x + 1) + (x + 3) = 8

2x + 4 = 8

2x = 4

x = 2

looks like the question has some typos.
