If the first 4 terms of a geometric sequence are left curly bracket 5 comma space 20 comma space 80 comma space 320 right curly bracket, then the formula for the n to the power of t h end exponent term in the sequence is .

answer:     true

step-by-step explanation:

y= 2x+7

changed to y= 5x +7

as slope is increased from 2 to 5

therefore it would be less steeper

so, option d) is correct

cross multiplying, we get :

⇒ (3) × (5) = (9) × (x)

⇒ 15 = 9x
