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
The answer is the morning temperature was 5 degrees above the afternoon temp.
Given that Mary has 2 bags of sweets. each of which contains same number of sweets.
Let us assume each bag contains x number of sweets.
After eating 4 sweets, total number of sweets left in two bags = x+x-4=2x-4
But given 2x-4 = 30
2x-4+4 = 30+4
2x=34
Hence there are 17 sweets in each bag at starting.
Answer:
Step-by-step explanation:
Amount loaned = $10,000
Interest rate = 3%
Duration = 6 years
10,000 / 100 x 3/1 × 6
= 300 × 6
= 1800 + 10,000
Total Amount to pay
= $11,800
