Answer 1

Answer:

1,835,000

Step-by-step explanation:

Sequence formula: an = a1⋅r^n−1

a1 = first number in the sequence

n = the term you're trying to find

r = ratio it changes by

7*4^10-1

7*4^9

= 1835000

Answer 2

Step-by-step explanation:

To find the "nth" term of an arithmeticsequence, start with the first term, a(1).Add to that the product of "n-1" and"d" (the difference between any twoconsecutive terms). For example, takethe arithmetic sequence 3, 9, 15, 21, 27....a(1) = 3. d = 6 (because the difference between consecutive terms is always 6.
