Chapter 5: Loops Problem 1 Pentagonal numbers A pentagonal number is defined as n(3n-1)/2 for n 1,2,, Hence, the values of the first few numbers are 1,5, 12, 22, 35, 51.... Write a program that prints all Pentagonal numbers within a lower bound and an upper bound entered by the user, see given sample input/output. Sample input/output: nter Lower and Upper bound (integers) 1 100 nter Lower and Upper bound (integers) 22 150 entagonal Numbers from 1 till 100 are Pentagonal Numbers from 22 till 1se are 1 5 12 22 35 51 70 92 2 35 51 70 92 117 145
