Question

Here is a rule for continuing a different sequence. ADD 4, THEN MULTIPLY BY 2 The second term of this sequence is 20.  What is the first term? ​

Answer 1

Answer:

The first term is 6.

Step-by-step explanation:

Let the first term be 'x'.

The second term will be (x + 4) * 2

Thus,

(x + 4) * 2 = 20

x + 4 = 10

x = 6

Therefore, the first term = 6
