➷ Substitute the first 3 values in (1, 2, 3)
(1)^2 + 20 = 21
(2)^2 + 20 = 24
(3)^2 + 20 = 29
The first 3 terms would be 21, 24 and 29
For the second part, just keep going on until you reach 50
(4)^2 + 20 = 36
(5)^2 + 20 = 45
(6)^2 + 20 = 20 = 56 (this is larger than 50 so it doesn't count)
It would be 5 terms
