Answer:the first term is 6
Step-by-step explanation:
We would apply the formula for determining the sum of n terms of an arithmetic sequence. It is expressed as
Sn = n/2(a + l)
Where
n represents the number of terms in the arithmetic sequence.
l represents the last term in the arithmetic sequence.
a represents the first term in the arithmetic sequence.
From the information given,
l = 204
n = 12
Sn = 1260
We want to determine a. Therefore,
1260 = 12/2(a + 204)
1260 = 6(a + 204)
a + 204 = 1260/6 = 210
a = 210 - 204 = 6
Answer:3,000,000 = 3 × 1,000,000 = 3 × 106. Notice that the exponent is the same as the number of zeros following the 3. Three million is a verbal expression, 3,000,000 is a decimal expression, and 3 × 106 is scientific notation.
