Question

Find the thirtieth term of the following sequence.

-6, -4, -2, 0, ...

52
64
66

Answer 1

You are adding 2 each time.

You are trying to find the 30th term, in which 4 are shown.

Subtract 4 from 30

30 - 4 = 26

Multiply 26 with 2

26 x 2 = 52

Add 52 to the last number given (0)

0 + 52 = 52

52 is your answer

hope this helps
