Question

What is the first four terms in the multiplication or ,geometric , pattern in which the first term is 2 and then each term is multiplied by 7

Answer 1

Sequence will be 2, 14, 98, 686.

Explanation:

Since we know in an geometric sequence the terms are in the form are

`T_(n)=a(r)^(n-1)` in which

a = first term

r = common ratio

n = number of term

Now from this expression we can all terms of the sequence

in which a = 2 and common ratio r = 7

The sequence will be

`2, 2.(7), 2.(7)^(2),2.(7)^(3)`

Or 2, 14, 98, 686

So the answer is 2, 14, 98, 686.
