Chapter 5: Loops Problem 1 Pentagonal numbers A pentagonal number is defined as n(3n-1)/2 forn-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) 22 150 Pentagonal Numbers from 22 till 150 are nter Lower and Upper bound (integers) 1 1e entagonal Numbers from 1 til1 100 are 15 12 22 35 51 70 92 35 51 70 92 117 145
