Simplify the <u>expression</u>
Answer: 20
Step-by-step explanation:
First is 6 x 3 which is 18 then take away 5 so it would be 13 and + 21/3 is basically a seven so its <u>20</u>
In a Geometric Sequence,<span> each term is found by </span>multiplying<span> the previous term by a </span>constant<span>. For this case, the constant is 4. To find the sum of the geometric sequence with 8 terms, we use the formula as follows:
</span>∑(ar^k) = a ( 1-r^n) / (1-r)
<span>
where a is the first term, r is the constant, n is the number of terms
</span>∑(ar^k) = 4 ( 1-4^8) / (1-4)
∑(ar^k) = 87380
