Which expression is equivalent to 16 × 3?
a) 3 × 16
b) (10 + 3) × 6
c) (16 + 3) × (3 + 16)
d) (3 × 1) + (3 × 6)

A

Step-by-step explanation:

X times Y = Y times X

The order doesn't matter.

the answer to A) is equivalent to 16 x 3

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.
