y = 40 * (-2) ^ (5-1)
= 40 * (-2) ^4

72,90
Step-by-step explanation:
Since 9 is the biggest number so list multiples of 9 between 55- 101 range.
Which are 63, 72, 81, 90, 99. Any number that is a multiple of 9 is a multiple of 3 because 3x 3 = 9. 9 is a multiple of 3.
Any even number is a multiple of 2.
Only 72 and 90 are even numbers.
So 72 and 90 are numbers divisible by 2, 3, 9.
