Question

Find the missing terms of the arithmetic sequence

Answer 1

the missing terms are -2,3,8

Answer 2

missing terms are -2,3,8

Explanation:

-7, ?, ?, ?, 13

To find missing terms we add last two term and divide it by 2

so that we will get middle term

`(-7+13)/(2) = (6)/(2) =3`

so sequence becomes

-7, ?, 3, ?, 13

Again we add -7 and 3 and then divide it by 2 to get middle number

`(-7+3)/(2) = (-4)/(2) =-2`

so sequence becomes

-7, -2, 3, ?, 13

Again we add 3 and 13 and then divide it by 2 to get middle number

`(3+13)/(2) = (16)/(2) =8`

-7, -2, 3, 8, 13

So, missing terms are -2,3,8
