Find the missing terms of the arithmetic sequence

the missing terms are -2,3,8

missing terms are -2,3,8

Step-by-step explanation:

-7, ?, ?, ?, 13

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

so that we will get middle term

so sequence becomes

-7, ?, 3, ?, 13

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

so sequence becomes

-7, -2, 3, ?, 13

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

-7, -2, 3, 8, 13

So, missing terms are -2,3,8
