1. 25, 43, 61, 79, 97 (7+18n, where n=term #)
2. 87, 65, 43, 21, -1 (109-22n, where n=term #)
3. 21, 35, 49, 63, 77 (7*(2n+1), where n= term #)
4. 64, 56, 48, 40, 32, 24 (8*(9-n), where n = term #)
5. 61, 66, 71, 76, 81, 86 (56+5n, where n = term #) <---- seems right

add the two numbers with a space between like (25 and 61 for #1) and (87 and 43 for #2) and then divide it by 2 so you know how much ur suppose to add or substract
the pattern is going at a steady rate, so once u figure out how much its decreasing or increasing by you just add it to the # before
