Define the type of sequence below. 7, 14, 28, 56, 122,

 The given sequence is a GEOMETRIC sequence with first term 7 and common ratio 2.

Step-by-step explanation:  We are given to define the type of the following sequence :

7,   14,   28,   56,   122,   .    .   .

Let us denote the n-th ter of the given sequence by

Then, we see the following relation between the consecutive terms of the given sequence :

Therefore, we get

That is, there is a common ratio of 2 between any two consecutive terms of the sequence.

Thus, the given sequence is a GEOMETRIC sequence with first term 7 and common ratio 2.

sorry

step-by-step explanation:

sorry, but im pretty sure its a now that i look at it
