Answer 1

Answer:

ans is 1

Step-by-step explanation:

8*7 = 56

56 + 1 = 57

5 * 7 = 35

35 + 1 = 36

3 * 6 = 18

18 + 1 + 19

1* 9 = 9

9 + 1 = 10

1 * 0 = 0

0 + 1 = 1

Answer 2

We must recall that:

Sequences are the grouped arrangement of numbers orderly and according to some specific rules

Given: $87,57,36,19,10,...$

$8\times7+1=57\\5\times7+1=36\\3\times6+1=19\\1\times9+1=10\\1\times0+1=1$

Hence answer is $1.$
