    5, 13, 21, 29, 37... difference between each term = 8, 8, 8, 8... i think i see the pattern ;)

    there are 2 types of sequences: arithmetic with a common difference and geometric with a common ratio

    perfect, so "the sequence begins at 5... then increases by 8... with each new term"

    it's ok :) so we got one term... two more terms to go and since we are increasing by 8 all the time we solve 45+8 = ?

    5, 13, 21, 29, 37... 1st term = 5 2nd term = 5 + 8 = 13 3rd term = 5 + 8 + 8 = 21 4th term = 5 + 8 + 8 + 8 = 29 5th term = 5 + 8 + 8 + 8 + 8 = 37 6th term = ??? 7th term = ??? 8th term = ???

    6th term = 5+8+8+8+8+8 = 45 7th term = 5+8+8+8+8+8+ 8 = 53 8th term = 5+8+8+8+8+8+ 8 + 8 =61

    Our sequence is increasing by 8 and by following that pattern, we retrieve the next three terms which is 45,53, and 61
