-90

Step-by-step explanation:

pre means before

predecessor means 1 number before that number

successor means 1 number after that number

Answer 2

Step-by-step explanation:

Concept:- There are two certain categories as follows:--

1. Predecessor:- the number just before given number

2.Successor:-the number just after the given number

Way 1,

In order to find the predecessor,

Just substract the number by 1

Ex- 8 - 1 = 7

Way 2,

IF U HAVE PROBLEM IN SUBSTRACTION

OF NEGATIVE NUMBERS like -7-1= -8

Just draw a number line,

Choose zero, at any point on number line,

IMPORTANT POINT:-

1.Take left of it as negative

2.Take right of it as positive

DONT GET CONFUSED WITH THE ABOVE TWO POINTS ......like me when i was in 3rd-4th standard

in this case,

WAY 1

-91 - 1 = -92

WAY 2

USE NUMBER LINE
